Slab or roof tool generally. Slab tool if the whole project has horizontal ceiling, roof tool for all ceilings if there are also sloping ceilings.
If you mean for tile based system ceiling, haven't done any of those in a very long time, but I suspect the overhauled curtain wall tool offers you a lot more options in ArchiCAD22. Also in 22 you have quite powerful tool for definining custom properties and by setting up IFC mapping rule, you can probably get some good results there: make a custom property based on a rule >> map the IFC property from the custom archicad property.
Regarding holes: if they are there for MEP, I would use an object to define the hole. If it is just a big hole in the design, model the hole.

1. You cannot use the Magic Wand to define the boundary, like you can with a Roof or Slab.
Here is a tutorial, from which I always do ceiling based on it, and never had issues with that.
Also for all holes you have in Object tool libraries to put on ceilings - lamps, ventilations, air conditioners, holes etc.
Watch the ceiling tutorial, or maybe I didn't understand what you needed.
