We were in the 50's- loop D- and still enjoyed privacy not shade though. We walked around through all of them and they all have a good amount of space.
I'd go for the ones with trees. There was a lot of beetle kill that took out many of the trees, so there are many with no shade. You can see photos of each campsite here: https://www.campsitephotos.com/campground/co/prospector/ Or check out by satellite on recreation.gov
