There is another option, you can pour a frost protected slab. Most common way is to put styrofoam under the slab, can also use a non-frost suceptible fill like clean crush to build up a pad.
I built my shop with thickened edge on a rubble trench style. It was meant to be heated but went through the first winter as a bare slab, no building on top. Didn't move at all.
Agree, I'd do both
Floating Slabs work, if ther is uniform drainage under the slab and chrushed stone, drainage sand, etc and foam as a cushion. Rebar the perimeter. The idea is the whole thing floats.
