The point is aesthetics. 32t is mountain bike cog.
My main cassette is 11-28 so it's all good in the aesthetics department and I can still have the mid cage if I want put a 11-32T cassette ocasionaly ;)
Are the crane creek HS's good? I always think meh when I think about CC, something like FSA...
11-28 should be sufficient tbh. It's similar to 10 sp 11-25 with a 28t at the back.

Check cane creek's headset offerings for low stack headset.
