My recommendation is to just try bunch of them and see which one fits your needs or you like using the most.
Try both manual tiling and auto tiling for both X11 and Wayland, one will eventually stick.
I started with AwesomeWM, then tried bunch of other ones , and to my surprise, I found myself using DWM (flexipatch) the most. I’m planning to transition to Hyprland soon.
Just use what you like and don’t pay much attention about the reviews.
While I didn’t have problem with mouse scroll not working, I did run games that had only audio and a black screen when window is unfocued. Try running the game in the same resolution as the desktop one at first, if that doesn’t work, other solution would be to use the windowed fullscreen or even windowed mode in game.
I use WM so this might not apply to the DE, but give it a shot.
