I’d stick with PopOS because it is noob-friendly and makes installing Nvidia drivers a breeze compared to a lot of other distros. If you ever feel more comfortable with Linux you can still make the switch to something else, but I don’t think there will be many reasons to do so as long as you like PopOS and get everything working the way you want.
In the meantime you can just read about other distros and if you come across a good reason for switching, you can consider it then.
This what I do and it works pretty flawlessly. I’ve never used Bottles or Lutris since I started adding the games to Steam. It also takes care of controller support.
