I have the same issue and we had this discussion several months back.
My personal build of Emacs v26.3 used the LUCID toolkit and doesn't
support XWidgets.  I tried installing GTK on my Chromebook (in the Linux
VM), but I couldn't get the Emacs build process to find/use it (helpful
hints?) 

Perhaps the Emacs Info pages need a small discussion on fonts and the
functions to use (beyond menu-select-font) and their expected effects?
For instance, more information about mouse-select-font for people who
can't (or won't) install GTK.

This is helpful, but people not knowledgeable about fonts may not
understand "some such".  ;-)
