Generally speaking, most if not all hardware running Win 10 will be able to work on any Linux distribution making a few exceptions where external drivers can be found. Normally though, this will not be necessary as it will be pre baked into the kernel with no interference from you

That being said - Mint runs an older version of the kernel compared to the current state of desktop Linux and may not contain certain drivers for hardware that came out after that specific kernel version was released. You can use a distro that favors being up to date over long term support, such as Fedora or Arch (if you’re willing to put up with setting up Arch) if that crops up. But generally, if you’re running win 10 still this shouldn’t be a problem

Without knowing your hardware, i can’t really say more though. Just try mint or any other distribution on a live usb and if it works there, then it will work when installed

Yeah. The behavior i stated was how it works in Gnome. In KDE since Xorg passthrough is a formal thing, the behavior is different based on those options

Xorg global shortcuts will work for anything using Xwayland, but not in anything thats wayland native

For example, in a game (using wine, which uses Xorg by default currently) your global shortcut will work. But in a wayland native window like Firefox, it will not if its the active window
