FWIW, I have a close relation that matches the pattern you’re identifying, and they have had very positive results from Internal Family Systems Therapy.
+1: this comment describes me and I'm actively in internal family systems therapy. took me a while to get used to the style, but it's been beneficial for me.
I think the therapist’s personality might have an impact (I could see certain aspects of it feeling a little “woo”), but it has been useful to frame and work through certain emotions/reactions/situations in a productive manner. My email is in my profile if you want to reach out.
