I couldn’t get the proprietary nvidia drivers to work with any wayland implementation except weston. Cinnamon worked fine, Plasma X11 worked but was unstable. I eventually gave up and fell back to nouveau and now Plasma wayland works A-okay.

Also I was not impressed with discover. It works, but it’s kind of slow and I didn’t really see an advantage over aptitude

edit: meant to specify that I was using the 500 series drivers that are new enough to support GBM, that’s pretty important

I can’t speak to Nvidia issues as I don’t have an Nvidia card installed, but as of Debian 12, they do allow for the installation of proprietary drivers which was often an issue in prior releases.
