Just get normal emulsion paint will do, such as ICI maxilite or equivalent.
But make sure the painter don't add cc powder to the paint, then you should safe from powdery problem.

Yes, contractor tend to use maxilite for ceiling painting, due to it is cheap. But if they follow the specification to paint, it will not be powdery.
One of the reason it become powdery is, the painter mix the paint with c.c. powder, which increase the volume of paint and decrease the quality of paint.
Tips for everybody, ceiling paint is more likely to mix with c.c. powder as compare to wall to cheat us. Reason being, we can touch the wall anytime but not the ceiling (Unless you use a ladder/chair).

Yup, that will reduce the tendency of it.

If paint maxilite follow the manufacturer's instruction, that will not be powdery.

More or less yes. Ofcourse you still can look for other brand like Seamaster, SKK or PAR. They are not bad too.

ICI maxilite or Nippon Matex are both reasonable good and economic options that you might look into.

If budget constrain, just apply 2 coats of the paint will do.
