Well, it slightly depends on who called you. Are you IP or OOP? What player type called you?
Board texture isn't the only thing you should take into account when cbetting.
Regardless though, medium strength hands aren't ones I'd be choosing to cbet with. I'd rather c/c. Having the 9c does make me slightly more inclined to cbet, but only slightly.
(I'm referencing the flop. I'd never double barrel pocket 9's on this board unless I bink a 9.)
