well, I'm thinking any 33mm CX tire should work unless you are really tight. I've used Schwalbe G-One in their CX version, and they are about the size of my 32mm tires.
That said, I spend most of my skinnier time on Conti GP5000 slicks (32mm). Personally, I've worked on developing a smooth pedal stroke and can do just about anything with slicks, short of real greasy stuff (wet rocks, roots, grass).
There are 30mm CX tires too (or used to be). some are mud some are semi-slicks for gravel riding on traditional road bikes.
