One place you might consider is
Enjoy your Stay @ Coral Estate Luxury Resort Curaçao
It was formerly the Habitat dive resort, which was an awesome place in it's day where we stayed a bunch of times. And a nice compromise location between the far west end boonies and the city. Got run down and sold, tons of work was done on the place and it looks very nice now. Don't know details of the on-site op Coral Divers, or what the diving is like there now, but I think they have a good rep.
Habitat was more marketed to the US, the new place more to the Dutch market, so you tend not to see much about it here anymore. But might check your boxes.
