Create a peripheral false ceiling with curved corners using fillet

Draw an inset rectangle on the ceiling, round its corners with the Fillet tool, then set the drop depth and material.

1. To create a peripheral false ceiling: select the ceiling, go to Create False Ceiling, then Add Extrude Shape, draw a rectangle corner to corner and Offset it inward with Copy by the band's width. The rectangle alone gives one filled shape over the whole ceiling.
