If you’re reasonably good at using and troubleshooting an operating system like Windows then you’re proficient enough to make the switch. Linux is at the point where there are versions designed to be as Windows or Mac-like to ease the transition, such as Linux Mint, and having to go to the command line is largely unnecessary.
chrome is definitely has a desktop environment your desktop environment is what provides stuff like the main bar along the bottom, the login prompt, and the wallpaper. a window manager ONLY places windows on the screen and requires external packages to do things like display a task bar etc. chromeos’ DE doesn’t provide the desktop as a place to store or manage files but it does have one.
a window manager places windows for applications on the screen and handles scaling and stuff like that. a desktop environment has a window manager, as well as bundling together other things like a sign in screen, displaying wall papers, a task bar, utility applications like a file manager and network setting manager . if you install a standalone window manager you also then have to install and configure all the auxiliary pieces yourself
