I believe I remember seeing a method a few years ago in a simulation class for eQuest where the instructor modeled the FLR-FLR height as follows:
This way you get the correct volume for plenum and zone & the correct-ish surface transfer and height location for the construction accounting for any difference in insulation where the slab meets the exterior wall.
This always seemed like a lot of work when I saw it originally, but would be interesting to test the two cases.
P.S. I know DesignBuilder allows the user to draw the geometry based on Exterior Surfaces (walls, roof, floors, etc.) and then by way of construction assembly thickness can either simulate the "inner" (net) or "outer" (gross) floor areas, surface areas, and volumes indepently. But that is another skinned cat.
