I don't think cut planes or show on storeys will get you a single plan to show you exactly what you want.
As you have discovered, if you can get it to work with one view (site plan) it may not work with others (floor plan).
I would make separate views of what you do want to see (i.e. cars on storey 0 and roof on storey 2), and then overlay these as drawings on a layout page - to build up the view that you want to see.
It may not work, but give it a go.
It may even be a case of using the other settings as well as multiple overlaid drawing on a layout.
