fc-match returns a single match.  Also, emacs does know about fontconfig
aliases (info "(emacs) Fonts").  The problem is that specifying an alias
name as the family attribute doesn't always work as expected (because
emacs font selection weighs font attributes in a different way).

For example, on my system

$ fc-match Serif
NotoSerif-Regular.ttf: "Noto Serif" "Regular"
$ 

However, if I customize the Info-quoted face replacing "courier" by
"Serif" I get

xft:-unknown-Sawasdee-normal-normal-normal-*-13-*-*-*-*-0-iso10646-1

Not a big problem, but just to elaborate a bit on Glenn's suggestion.
