Done a lot of building and a lot of concreate work. I agree with Pete, no broom finish, will trap a lot of dirt and glass dust. My one concern is with the underfloor radiant heat. If it is the plastic pipe in the concrete I am not sure how that would behave under the furnace. I would check with the manufacturer and make sure there is some heat barrier between the furnace in the floor. If it is a fluid system it may transfer heat the the rest of the shop when it is not running even in summer. Over time that part of the floor picks up a lot of heat. Not sure how the pipe would behave. For a floor drain there are specialized traps but you have to be diligent about cleaning them. If you do put in a drain go oversized both in pipe size and trap size. Also make sure you have a good cleanouts in the pipe run.
