Is the first step really needed?  Cantarell should already be part of
gnome-service-type.

In any case, troubles with fonts are to be expected under some
circumstances.  See `info "(guix)Application Setup"', particularly
paragraph 2.6.3 X11 Fonts.  Your issue also has probably little to do
with linux-libre but rather the fact that an update from pre-5.18 to
now brings in lots of package changes.  IIRC the great Cantarell break
was a rather recent event, though I'm not sure what caused it.
