Welp, there's your problem. I have an NVIDIA card as well and it's been the source of at least 95% of my Linux headaches.
I've tried a few distros and Linux Mint was definitely the most "just works" for me. Make sure you're using the proprietary NVIDIA drivers, regardless of what option you choose. Currently I use SpiralLinux (Debian with a few tweaks) because I really like the BTRFS snapshots and fell in love with KDE during my distro-hopping, but Mint is what I would recommend to the vast majority of people.
Mint is a pretty solid choice for like 95% of people. If you're already using LibreOffice then you're halfway there, and I've been able to run all the games I want through Steam or Lutris (the Flatpak versions are better for compatibility IME). A lot of people use Bottles for games as well, but I've never been able to get it to work properly. I think I started using Linux full-time at about the level you seem to be at, and I didn't run into any major issues.
