ChromeOS is also Android basically, no?
So.. GrapheneOS in desktop mode. I don't know the details, but there's that I think. Kinda just hook up the phone to a dock with a monitor. Great option, more secure than linux.
You can try a regular linux distro with gnome. It's a normal OS nowadays. I don't see anything more or less complicated. Windows is more overwhelming imo with all the bloat you have to remove with some scripts downloaded off some russian forum, and all the settings within settings..
