My knowledge both of Fedora and Nvidia are both a bit dated. So if anyone “um actually”''s me, probably defer to them. But last I knew you want to get nvidia drivers from the rpmfusion repo. Relevant link: https://rpmfusion.org/Howto/NVIDIA.
As others have mentioned there’s no need to remove flatpak.
Otherwise, sounds like you’re on the right track to me.
Edit: I just read a comment about breakage with Fedora flatpaks. So perhaps prudent to remove if so.
I am but a single humble meatbag that enjoys games and can’t speak for all gamers, but I generally dislike the typical “gaming rig” aesthetic. I don’t want RGB lights. I don’t like ostentatious looking cases or accessories. I do find it tasteless, to reuse your term.
No sleight on those that do though. If that’s your style, then enjoy it!
