If you’re looking for smaller try an XE-4 or a used XE-3.

Might be hard to find a new XE-4. After all the X100V cams sold out, the XE-4 was next.

Do you need an ILC? If not, consider a Ricoh Grlll or lllx. The smallest APS-C camera around. I have the X. Fantastic film sims, as good if not better than Fuji, althought not as many. I like the Fuji sims, but sometimes having more choice isn’t always better.
