I should have been clear in my question.

I didn't think about what plywood to use but comments on this would be
welcome.

And what kind of coating to use.

I used porch/deck paint before and it didn't hold up well but at the
time the shop floor got a whole lot more abuse than this one will.

Moved last year to a place with no shop so I need to build one now
that most everything else is done. It will be concrete slab on grade.
I will use 2 X 4 sleepers on the concrete with plywood over the
sleepers.
My last shop was done this way and I liked being able to run airlines
and some wiring under the floor.
Somewhere I saw a picture of a shop with a plywood floor and the
plywood had 2 or 3 coats of poly on it.
Anyone on the list use this approach.
