kind of awkward without a read, but I lead this turn..
A PF cold call is rarely done with QQ/66/88 or anything that has two pair on this flop (maybe Q8/68)?

I dont really know what to make of a flop cap in this spot against an unknown.. I could see a decent amount of people doing that with QJ/QT/Q9 with jt9 of diamonds... Maybe even a midpair with a diamond.. VS other players its a monster or A of diamonds (which you have)..

I dont think it makes a big difference c/c or b/c on the turn without a read. c/r is by far the worst of the options.

I just call the flop raise too... You may have a tiny edge, but the disadvantage of narrowing your range, decreasing your implied odds and getting popped UI on the turn now that youve retaken intiative offsets your equity edge enough that id want to play it passivly.
