I think with KQs you can bet 3 strteets for value and expect to get called down by worse hands or easily see him c/r there with air, since board is so dry.
So if you´re generally going to c-bet with your air I think you can also c-bet with KQs.
Hands like QTs or JJ you can check behind, since then you really don´t like seeing c/r and rather go 2 or 1 street for value
I might even raise turn for value and bet also river, but if you went to pot control you can also just call him down
