Not super well supported, but there's a Samsung Dex app for Windows and MacOS (I think unsupported now) that let's you plug your phone into your computer, and get Dex in a window. Runs the phone apps on the phone, gets your android store etc. but you get an "ok" minimal desktop that lets you do your phone stuff with a mouse and keyboard.

After I figured that out I basically dropped all the run Android on a desktop things.
