Struggling with shaft lean and compression

I've struggled with flipping at the ball for years now and I've never had any shaft lean and compression. It works okay with shorter irons but longer irons are impossible. I've also struggled being over-the-top but have fixed it by getting a feel of dropping the clubhead/club behind me in transition.

After watching GSA videos, I've diagnosed that it's my open club face that has been forcing me to flip through. so I've worked on "motorcycling" down as we get to impact to force the bowed wrist and not flip. I'm still not getting good contact and distance has dropped quite a bit without the feeling of me flipping through at impact for extra power. I'm looking at the front facing videos I'm not really seeing too much shaft lean even with this feeling.

What am I doing wrong?

I was also playing around with some of the feels you talk about, and when I supinate through entirely with my hands/arms, I can see pretty good shaft lean. But this completely stalls my rotation and the shot is usually really weak distance and left. If I add rotation with this hand supination through the hit, the ball pulls even harder.
