hi,
first, i would speak to the inspector. then quote the code.
i think building construction dictates wiring methods..
take for instance a three story dormitory..this may be considered a place of assembly..it is built out of wood and wired with romex...i would be shocked if your inspector would require this building to be wired with a/c cable? even motels get romex..
i would use romex if the ahj will go along with it..if not a/c cable is not too bad but it is more expensive, time consuming and whole lot dirtier..
good luck
-regards
