I think it depends on layover time.
we did SFO-EWR-YYZ on a late afternoon flight, arriving late evening and departed first thing in morning I think total time on ground was like <10 hours. Bag tag printed off with both segments. Agent had to do something to short check, and happened to be training another agent, IIRC I remember them saying something about 12 hours being the cutoff, but since it was overnight they could override for short-check.
A multi-city ticket might price out ok if it’s last flight of night into DEN and first flight out. YMMV.
