These appear to be the highlights. There's also other galleries in https://www.nasa.gov/gallery/ with a bunch more photos:

If you're into this, check out the Apollo 11 gallery[1]. Contains very high-quality images from the actual trip, including "not so common" pictures from the moon.

They all seem to be a disappointingly low resolution, unfortunately.

On the day of the splashdown, I visited the official NASA Space Shop, and I was met with an announcement that the availability of Artemis gear is severely limited "due to unprecedented demand" and there is still a "delayed shipping" notice up there.
