It's perhaps less in keeping with typrographic convention/thinking to consider the distinction "This is my sans serif font, and this is my serif font"
as it would be perhaps
"this is my display font, and this is my body font"
(Or "this is my primary display font, and this is my secondary display font, and this is my body font).
With that in mind I propose rather than:
$font-sans;
$font-serif;
using
$font-body;
$font-display;
It's a small and perhaps inconsequential thingk, but sine this seems to be promoting in-medium styleguide-based design... then I think it relevant.
