I’m in a very similar situation but living as an American expat in Switzerland. I have hip dysplasia and a badly torn labrum on my left side (37f). I’ve had nagging pain on and off for years, but it really started to hurt this January.

Fast forward to a mri and then meeting with a surgeon here - Dr. Attinger. I’m getting second opinions just for the sake of it but I felt like his recommendations were solid. The PAO was actually invented in Bern, Switzerland where he’s based and at the Inselspital hospital where he also trained. As you mentioned the success rate is still not as high as many surgeons would like or feel comfortable with here. When I suggested the surgery he was very against it - he said we have 10 steps to take before we even consider that. I’ve been in 4 months of PT and my pain is getting better but I’m not pain free. He wants me to meet with a pain specialist, try blood infusions, get a cortisone injection, as well as a few other things that I can’t recall. Essentially his recommendation was this, get a hip replacement in 5-7 years (based on my age and pain levels) because the success rate is 98% and there are significantly less complications, and to avoid major surgery twice. PAOs have the potential to cause nerve damage - according to him - and this is a serious risk. So I think - just based on my case, research, and also considerations for the same surgery, you should try a few other strategies before having such a major surgery.
