To be clear, this question is for general PC use, and not only gaming.
Desktop mode on my Deck has easily become my favorite PC experience in a very long long time, and I use it more docked as a PC than for gaming. I’ve used Windows and Apple my entire life before now, so I have zero experience with Linux, other than the Steam Deck, but the OS is incrediby friendly to newcomers, and I’d say it’s essentially a modern and polished version of Windows 95.
So what would you recommend as a similar experience for desktop?
Edit: I should probably add that I’m an artist and designer, and play around with Blender and 3D modeling stuff, and maybe even some game dev at some point. So Adobe support, and GPU Blender support would be superfantastic.
Since desktop mode is basically just KDE but without the ability to install software packages you could try Fedora.
They do a version just like desktop mode that has you install everything through the store, or you can get the regular variety to get a bit more flexibility.
Personally I’d steer clear of anything special as your first Linux install. Go with standard Fedora, then you can experiment and branch out if you’re interested, but you don’t have to if you like what you’ve got.
