I don't know what defines "the average user", but the average user does not use a mouse that requires proprietary software for its side buttons to work, in my experience.

Maybe try a distro that is known for compability with NVIDIA such as popOS or bazzite. I have used both for the last 4 years, and other then some specific games where anti-cheat or kernel level anti cheat is an issue (and honestly, fuck those games anyway because those developers spend extra effort to make sure their games dont run on Linux), the rest just works flawlessly.
I am sorry, is your mother in law really buying logitech mouses that specifically require a software to run even on Windows?
