I think I have 5 different carry-on bags in differing levels of usability. They are small and compact, and I tend to use them for most of my travel even if I don’t have to go on a plane. I’m small, so my clothing is not very big, and I can pack quite a bit into a rolling case to go anywhere.
Carry-ons vary in style from bags that are literally carried (like duffles) to newer alternatives that have in-line skate or spinner wheels. They have to stay under 21 inches in order to fit in an overhead compartment, and there are plenty of options on the market that cater right to this niche.
The following are a pretty solid idea of what you can fin in carryon style.
