Welcome and congrats on the new purchases. Sounds like you're going to have a first rate shop. Personally, I'd go with the wood floor. My scroll shop is 1/4 of a 2 car garage and the concrete floor was SO cold in the winter. Hubby installed a raised wooden floor and it's so nice...think he may have even put some insulation under it, but not sure.
The only problem I've had with the wood is that where my desk chair and chair at the saw roll, they were wearing into the grain of the plywood. Solved that by one huge floor mat. Since the desks are in corners and the chairs sort of back-to-back, one 60X80 mat did the trick nicely. Now they both roll without destroying the floor.
You'll find that with a bit of practice, you're going to love your new hobby. Lots of info here, all you have to do is ask.
