I personally use Nobara linux, which is redhat based and set up from the get-go to use for gaming. Compatible with AMD graphics and NVIDIA graphics as well. Its very customizable and easy to set up but on hindsight I shouldn't have used this OS as my intro to linux as a whole haha! It can get somewhat overwhelming with the options, most of which I can't understand :P
But, I can also vouch for what @moonlightwilderness said and vote for linux mint as a good beginner OS, same as "Pop!" OS.
