For typical buildings, the easiest and probably still the best way is going old-style by default, making all walls 'Symbolic' and showing them 'Home Story Only' (Wall Settings > Floor Plan and Section > Floor Plan Display) --and switching them individually to any of the other options when you need them specifically for some funky mezzanine or other multistory element situation.
When you have steps and split levels the floor plan drawing convention actuallly follows the levels, you don't have a true 'cut plane' for the whole floor/story. In that situation the 'cut plane' often makes a mess of the conventional floor plan representation.
