The MTB has a HT2 BB and I know what that fits. The road Bb is still square taper. What else goes into a "standard" BB shell?
BB30 for example? I assume press fit things go into the frame so won't fit my frame.
Too many choices now.

If you currently have a square taper then you will either have a 68mm British thread or a 70mm Italian thread bottom bracket. Bb30 and all other press fit bb's will not fit. You need the appropriate threaded bb either ht2, fsa megaexo, SRAM gxp/power spline, shimano octalink or another square taper depending g on what cranks you are using.

Ta. Was eliminating BB30 which is appearing on the cranks I was looking at.

Are Shimano BB30 cranks compatible with 'standard' (screw-in) hollowtech HT2 bottom brackets (and vice versa)?

Bb30 is a 30 axle. Ht2 is a 24mm axle. You can get adapters to make a ht2 fit bb30 but not the other way round. FYI shimano don't make bb30 cranks.
