First of all, congratulations!
Does your contractor/architect/designer know that you intend to load up this new shop with several tons of cast iron? Has that been calculated into the design of the girders and joists? You'd rather find that out sooner than later.
There are sources of supply here in my area for wood flooring for trucks, rail cars, etc. Utility grade, generally (here at least) something related to oak. Pretty inexpensive, durable stuff. Sometimes sealed, generally not 'finished' in the sense of what you would have in your den, although you could, if you wanted. All depends on what you are going for. In trucks, it's often laid on edge, like gluing up a workbench top. That would add a lot of rigidity to the floor, and it would last forever.
My shop has to be able to revert to being a garage, when we sell the place. So concrete is what I live with. And since everything gets moved around, often, I don't use the padded mats, although I should. Wood floors are reputed to be much easier on feet and knees, as well as on edge tools responding to the call of gravity.
