Nobara is probaly a good choice, never used to be but looks good.

Only issue about linux gaming is anti-cheats, like if your friend wants to play valorant, r6, fortnite, or any new call of duty game, hes kinda screwed. You also have games like apex which work now because EAC supports proton, but ever since EA made their own anti cheat, its only a matter of time.
