my therapist uses a mixture of dbt techniques (which is a development of cognitive behaviour therapy) and a self-psychology approach (which is psychodynamic though also in the humanist tradition, i guess).

there is a whole literature on trauma by people like Schore, Van der Kolk, Briere (might have spelt that last one wrong). He is informed by that stuff, I guess. He holds back a lot on the 'cognitive restructuring' aspect since I'm so hostile to it... He is fairly flexible with respect to doing whatever seems helpful...

Mostly it is about the fit between the therapist and the client. Part of that can be about you finding a theoretical orientation you like... But you know sometimes people are trained in one tradition but they are able to transcend that when needed in therapy. So... Dunno...

Some people interview potential therapists. see 10 or 12 and then decide who they seem to get on best with. That is one way to do it... good luck
