I agree with everything here, except for maybe the last part. Most Windows users I know have only ever used a single application for any given purpose, and having to find all the open source alternatives (or figuring out how to run them in WINE) can be quite a change. Granted, that isn’t really a Debian issue; that’s just part of moving to Linux to begin with. I’m not familiar with all the default packages in Debian, but so long as the desktop version has an image/video viewer, some default web browser for the user to look things up with, and basic utilities to open files with (mp3, doc files, etc.), I imagine the default packages will be fine for most. The lack of a GUI for Nvidia driver installs will of course be a point of friction for most, and maybe some missing media codecs (correct me if I’m wrong about those not being installed by default). I certainly think it’s not right to say Debian is “too lean”, just that it is “lean”.
