Based on the information you're giving, TMY-2 would be a pretty easy choice if you want finer grain than HP5. XTOL 1+1 would be great with it. Grain will be significantly finer than HP5, with good sharpness. If you want slightly higher sharpness, with a very small increase in grain 1+3 works well, but highlight contrast will be a little lower (not necessarily good or bad). You can of course alter these characteristics by changing exposure index, development times and agitation. Lots of flexibility.
