The Gnome desktop is a pretty good middle ground in my opinion. It is in my opinion even simpler than Windows to use and allows enough customizability with extensions. People in the Linux world love to dunk on it for using slightly more RAM and not having the same amount of customizability as other desktops like KDE Plasma.
I am honestly not sure as to what the benefit of that is compared to the approach of CalyxOS with MicroG. It has worked for me perfectly, except for one app, BeReal for some reason gives a pop-up telling that Google Play Services is missing, even though I already have MicroG fully setup and working. Other apps have all worked fine, including Google Apps like YouTube and my banking app.
