What I experienced is that Snaps/Flatpaks that contain X11 apps will behave very oddly in a Wayland sessions, at least with NVidia GPUs.
Using distros that still use X11, like Linux Mint, seems to help a lot.
One thing I will commend Snaps/Flatpak for however is bundling dependencies, especially deprecated ones. I spent DAYS trying to install an older version of .NET framework that's no longer supported to get a game (Vintage Story), but to no avail. With the appropriate Snap/Flatpak it worked first try, well, once I found the distro that doesn't have the X11 problem that was previously stated.
Win+P allows you to quickly change how your windows works. Win+K brings up the menu to connect to a wireless monitor. Win+L will lock the screen. Win+R will call the "Run..." window.
KDE Plasma also inherits a lot of the shortcuts Windows has. AFAIK MATE/Cinnamon do also share some of the keybinds, but for some reason they use CTRL+ALT instead.
Also fun fact: the Windows key is also called the SUPER key.
