Others have posted way more in-depth responses so I’m just here to provide some encouragement!
It looks like you’ve done your research if you’ve decided on pop. I personally use Fedora but I also don’t do much gaming so my needs are better met by it. Once you’ve gotten used to Linux, you’ll realize how little of a difference there actually is between most distros so don’t sweat it too much.
I wish you luck in your endeavors (pun intended) and I hope you find it suits your needs!
