Ubuntu based distros are going to have a very easy Nvidia driver experience (just open the driver tool from the start menu and select the version you want, and bam, done). However, one downside of Ubuntu itself is their pushing of snap packaged apps, which are considered a bit crap, and can cause weirdness (I think Valve officially don't recommend the Snap version of Steam).

You can avoid the snap stuff with Linux Mint, as they totally strip that out. Only downside of Mint is that it's still on an older LTS version of Ubuntu, 24.04 (the latest is now 26.04, two years newer). You will need to add an additional PPA (a third party repository) to access the latest 610 Nvidia drivers on it, which some of the very latest games like the James bond require to launch in Proton. That may or may not be an issue for you. Mint also has the best built in app store, IMO.

Fedora is nice, but the Nvidia driver isn't quite as easy to install, and it doesn't come with some needed video codecs out of the box, though this script maker can make those pretty easy to get. I'd recommend it if you want more up to date apps in the repos and don't want to encounter Ubuntu's snaps.

Nobara is a spin of Fedora with all that stuff included (and has an installer with the Nvidia driver pre-installed, I think), made by the Glorious Eggroll who makes improved versions of Proton.

I personally would suggest choosing between those options, since both Ubuntu and Fedora based distros have a lot of 3rd party support, such as Mullvad, which only supports those two officially, and they have large communities with lots of help.
