Will this mission consist of orbiting the moon (similar to Apollo 8) or a lunar swing by (similar to Apollo 13)?

Artemis II will not enter lunar orbit.
The mission's first day will be spent gradually increasing Orion's altitude in Earth orbit while the crew tests the spacecraft's systems. Assuming everything is working order, then the European service module's main engine will fire to send Orion to the moon and refine its approach during the four-day journey away from Earth.
The mission will come within 6,479 miles (10,427 kilometers) of the lunar surface and travel 6,400 miles (10,300 kilometers) beyond the far side of the moon before heading back to Earth on a free-return trajectory.

While the mission profile is more like Apollo 13 than Apollo 8, it's significantly different. And — not necessarily because of the difference — I think NASA (and the crew) will go to some lengths to avoid any comparisons with Apollo 13. (Remember STS-13? No, I don't either.)

There has been no indication (and no precedent yet set) for when we can expect to see the crew patch. The only thing NASA has said about the emblem is that it will be designed by the crew.
When the patch does debut it will be posted to a new topic under the Patches and Pins forum.

Interesting view of the heat shield. Am I remembering correctly that they redesigned it after Artemis I?
I don't believe I saw a metallic finish previously. I don't thinks it's a protective cover as the mounting pads look too big to allow it to be removed.

The Artemis I heat shield had the same metallic finish:
Technicians applied a coat of white epoxy paint to the heat shield's surface and then applied aluminized tape after the painted surface dried. The tape provides surface resistivity, and absorbs solar heat and infrared emissions.
To my knowledge, the heat shield was not redesigned between the Artemis I and Artemis II missions (I think there were changes made between the Exploration Flight Test Orion and Artemis I), but Lockheed and NASA are still studying unexpected impacts to the Artemis I heat shield that didn't match their models going into the flight. There was still plenty of safety margin so as not to require a change to the Artemis II heat shield, but modifications could be made for future Orion spacecraft.

Canadian Space Agency release
Canadian Space Agency astronaut Jenni Gibbons to contribute to future mission to the Moon
Today (Nov. 22), the Honourable François-Philippe Champagne, Minister responsible for the Canadian Space Agency (CSA), announced a significant assignment for CSA astronauts. Jenni Gibbons will serve as the backup astronaut for the historic Artemis II mission to the Moon.
Recruited as a CSA astronaut in 2017, Jenni completed her basic training in 2020. Since then, she has continued to serve Canada's space program and worked in different positions, including guiding spacewalks from Mission Control and overseeing commercial vehicle procedures and daily ISS operations.
In the event that Jeremy Hansen is unable to take part in the mission, Jenni Gibbons will represent Canada on Artemis II. Being part of this very select team will make her a key contributor to defining and validating the astronauts' training and processes for future Moon missions. Jenni will have the chance to influence how future Artemis missions will unfold and how to prepare for them.
Over the last four decades, Canada's astronauts have earned a world-class reputation. Jenni's assignment contributes to preparing CSA astronauts for increasingly challenging roles in space missions and cements Canada's reputation as a sought-after partner for space exploration. In doing so, she will inspire Canadians across the country and spark interest in STEM-related careers for countless young people.
"It is an honour to fill this role for my agency and my country to make the most of the opportunity afforded to us by our contributions to the international effort of lunar discovery," said Gibbons. "Space is for everyone: as Canadians, we recognize its essential nature in our day-to-day life, economic well-being, and commitment to technological advancement."
"As a part of the Artemis II backup crew, I will work to define and develop the procedures and architecture required for humanity's return to the Moon. I will be a crew test subject for critical operations from launch to splashdown and recovery. I will train as a capsule communicator, ready to act as the link between the ground team and the Artemis missions when in Mission Control. I will train alongside the crew and will be ready to support them in whatever capacity their mission requires. Finally, I will be prepared for future missions critical to Canada's space program. I look forward to bringing Canada with me on this journey," she said.

NASA's Artemis II Crew Meet with President, VP at White House
The first astronauts to fly around the Moon under NASA's Artemis program visited the White House in Washington Thursday (Dec. 14), and met with President Joe Biden in the Oval Office to thank him for his leadership and discuss their upcoming flight test. Artemis II crew members are NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen.

The mission is currently targeted for late 2024. After launching on NASA's SLS (Space Launch System) rocket from the agency's Kennedy Space Center in Florida, the crew will travel aboard the Orion spacecraft on a 10-day mission around the Moon, testing its systems for the first time with astronauts for long-term exploration and scientific discovery through Artemis. Driving both human and robotic exploration at the Moon and Mars, science is a key foundation of NASA's work.
The astronauts also discussed training and plans for their mission with the President, as well as lunar science, including a Moon rock on display in the Oval Office. That rock was collected in 1972 by Apollo astronauts Harrison Schmitt and Eugene Cernan, the last humans to step foot on the lunar surface. Samples collected on future Artemis missions will continue to help humanity shed light on how the Moon formed and evolved, how it interacts with the Sun, and how water and other resources arrived at the Moon and are preserved.

While at the White House, the astronauts also met separately with Vice President Kamala Harris, who serves as the chair of the National Space Council. They discussed how Artemis represents the power of technological innovation and international collaboration.

Figure 3 on page 9 of the OIG Artemis II Readiness Report dated May 1, 2024 illustrates the excessive char flaking on the heat shield. It is, to me, pretty disturbing.
I think (but hope that I am wrong) flying Artemis II next year might be optimistic.

Looks can be misleading.
First, it should be pointed out that as bad it may look, the charring and flaking was never a risk to the vehicle. There was more than sufficient margin for the heat shield to still function as designed.
Second, look at NASA's response (included within the same report):
Ground testing successfully recreated char loss in the arc jet facility using large-scale test panels of full-size Avcoat blocks. The recreated char loss has the same features as observed on the Artemis I heat shield.
The team is currently synthesizing the test results together with the leading theory for root cause and are planning formal presentations to the necessary technical forums in preparation for a recommendation to the Orion Program Control Board for Artemis II in April/May timeframe. The recommendation will include Artemis II heat shield operational capabilities based on the latest thermal analysis work.
An Independent Review Team effort planned for May 2024 will confirm the team’s recommendations to the program on the root cause, heat shield capability, and corrective actions going forward.
NASA expects the work on this issue to be completed by June, but even if that is optimistic, the Artemis II launch is more than a year away.

I would have expected the Artemis 1 re-entry profile to have been rather more challenging than a "standard" re-entry profile, in order to assess the heat shield safety margins. Was that the case?

If I recall correctly, the Artemis I reentry was designed to test a new profile ("skip reentry") rather than push the heat shield to its limits.

NASA is facing schedule challenges on multiple fronts for the Artemis II mission.
A new report from the US Government Accountability Office ... finds that the Exploration Ground Systems program had several months of schedule margin in its work toward a September 2025 launch date at the beginning of the year. But now, the program has allocated all of that margin to technical issues experienced during work on the rocket's mobile launcher and pad testing. ...
An independent review team has completed an assessment of NASA's work on the heat shield, but NASA has not publicly commented on these results or its decision moving forward. In response to questions from Ars this week about a decision on whether to take corrective action, an agency spokesperson said, "The Artemis I heat shield investigation process is still underway, so NASA has not made any decisions yet."
To prepare for the Artemis II launch next September, Artemis officials had previously said they planned to begin stacking operations of the rocket in September of this year. But so far, this activity remains on hold pending a decision on the heat shield issue. Asked when NASA now plans to start stacking operations, the space agency official said, "We are still tracking toward stacking beginning this fall."
