I'm not going to pretend I'm qualified to add, so I'll instead ask a couple of questions.

When we know the opponent raises cbets 30% does that qualify as an exploitable tendency? Or are people generally that aggressive at this limit with a balanced range? My immediate thought here is that his cbet-raising range has quite a lot of air in it, so it may be profitable for us to adjust by continuing with a decent amount of bluff catchers in our flop bet/call range.

Is this the correct type of adjustment to consider, and if it is, is T9o the kind of hand we want to put into our flop bet/call range? With his 24% bet river frequency it seems to me that he's more likely to bluff for small amounts on earlier streets and less likely to bluff for bigger amounts on later streets. This could give us a cheap/free showdown when we're best. However, if he does a lot of bluffing on earlier streets he'll end up on rivers often with weaker ranges and the 24% from this player might be less indicative of honesty than a similar stat would be from someone who tends to continue with stronger ranges.

Since we expect the opponents range to contain many weak hands (?), is it profitable to plan to bluff on a later street - or will T9s still be strong enough that it will not usually fall into a bluff range?

Given his propensity for raising the cbet, the flop being dry, potentially looking to pursue a bet/call line with some maneuvering later in the hand would there be an argument for cbetting smaller than normal? Or do we rather want to just term the raise from the opponent a mistake and cbet flop bigger to increase the size of his mistake?
