They recently (late 2022 maybe) released Gnome Tour which explains this stuff to new users. Admittedly it's too late for people already on Ubuntu or something, but discoverability of these features is getting better.

Even in this article they mention adding a widget that displays shortcuts.

I agree it would be nice if Gnome displayed keyboard shortcuts in tooltips. I don't think there's even a tweak to enable that unfortunately.
