I currently use windows 10 in my daily life. I often play games, use browsers, basic stuff like that. On top of that, I also experiment with different music software, mostly Reaper for now. I edit videos and images at a very basic level as well. Upon switching, what should I expect to change? I’m considering Pop!_OS seeing as its praised for its compatibility and easy switching. What’s the situation with gaming look like? I know gaming on Linux has been a HIGHLY discussed topic for a while, is it easy to play any (non triple-A) steam game? I’m nowhere near involved in computer science, I’d just consider myself more stubborn than most end-users so I can persevere through some basic problems.
Many things are very similar on Linux compared to Windows (e.g. Browsing, Steam). One big difference is that people prefer using package managers to install software (instead of downloading and installing it manually).
Pop!_OS is a nice distro and it should work well for you if you like the UI. There also many other good distros if you want to play around a bit. You can easily test them using a Live ISO.
I’d say that you can expect almost all games to work. The main exception are games with anti-cheat that decide not to support Linux. In my case, there has only been one game in the last two years that didn’t work (War Thunder crashes a lot more than on Windows). Playing AAA games is generally not an issue.

This. Especially for drivers, always use the package manager of your distro and do not attempt to manually install Nvidia drivers you downloaded from their website.
