Been trying to add more c/r to my game but wondering how to choose hands to use are more dry boards, or do we just not have a c/r range in these spots. Here is an example.

Say BTN raises and you call from the BB and see a flop of 65K rainbow. BTN bets, do you have a c/r range? Maybe 44 and 55 and some K5s for value and then bluffs. For bluffs would you rather have a hand like 89 for the gutshot or a hand like QJ with a DBFD that blocks more of V's continue range. Maybe some mix of both is better. Overall i'm just a little uncertain in these spots as I know I am not c/r enough in general.
