Linux community doesn’t help the user friendly nature of the OS, that’s true. Steam deck runs Linux so if it works on steam deck it will likely work on Linux mint or Ubuntu.

Lots of terminal help and outdated forum posts make it feel difficult to manage Linux, you’re right it is overwhelming and it’s not going to have full software compatibility, but if you spend lots of time in the browser and rely on web services it works fairly well over all and is generally low maintenance if you stick to the App Store and use graphic user interfaces.
