I've seen bmx looking fixie cranks, but they all seem to be like hollowtech sets.
External bottom bracket cranks are so much easier generally especially with Sugino and some others you don't need specialized tools to remove them and they are a much better attachment system. I was a square taper till I die person till I finally tried some Shimano cranks and had to install them and then was working on them more often and boom it was a game changer. No more crank pullers? Sign me UP! I still have a bike with a square taper crank that is a single speed but beyond that I think pretty much everything else is external BB mostly 24mm but have a new Campagnolo crank which is different.
I would get a crank you need to fixie in anyway though a single speed or fixed gear crank could work assuming a 68mm bottom bracket and enough clearance (as track bikes are 120mm and QR MTB is 135).
