KDE plasma has this feature. You can choose between forcing x11 apps to scale or allowing x11 apps to scale themselves. Some apps won’t scale at all when you do the latter option but most at least increase the font size or have their own way of scaling.

Firefox has librewolf for desktop.

it has something called sandboxed google play services. they claim its more secure and private than microg. also in my experience notifications and location is more reliable with it than microg. also you can disable the constant notification for apps like signal and it still works afaik.

GNOME is pretty much alone in offering no option for icons on the desktop. Distros like Ubuntu and PopOS use an extension to hring this functionality back and you can on any GNOME desktop yourself if you need to. Other DEs offer it by default.
