Remove rear toe that factory dial in to create understeeer as a safety net.
If you say it does not rotate with trail braking, there is something wrong with alignment or worn/tired suspension parts. I have zero problem getting a 997 to turn in and find it very neutral with throttle steering even with factory rear toe.
Where are you feeling the push the most and what type of turn?

Turn in/mid corner, mostly low speed corners like the Keyhole at Mid-Ohio. Sure trail braking helps, but you shouldn’t be forced to trail brake to get a car to rotate. Admittedly coming from an S2K the 911 will always underwhelm in this department, but I am confident I can get it closer to what I want with a few small tweaks.
Slow corners with long entry way you should be able to get turn in with a little LFB if you feel a slight push and with small back and forth steering inputs until front grips. Should turn if settled though. Cup car and GT3s can behave a little different so make sure getting advise from someone driving same set up as you.

Assuming a factory alignment, you can reduce understeer by minimizing rear toe-in (that will also reduce/eliminate inner rear tire wear).
But... contrary to what most 911 new drivers say... a properly aligned 911 does not push if driven correctly. Most new drivers over drive them approaching a turn and cause understeer. 911s should not be over-driven in any way. Of course class/early 911s even less...

I am not really interested in the “driver mod” suggestions. It isn’t arrogance it is just that I am confident in my abilities, between sitting in the right seat and driving, I would venture to say i have had more seat time than most people. I am probably a bigger critic of my driving than most and admit I can most definitely gain more experience with the car, but it does not handle how I want, which is why I made the thread. While I understand very well how to tune a suspension, I recognize there are many ways to skin a cat some better than others, so that was the real intent is to figure out the best way on a 997.

Like I said, not trying to come across as arrogant, I am just really interested in one thing and that is making this car handle a bit better. Totally agree part of it could be coming from a different car, but I do know that people who track the non-GT cars typically make adjustments. This car isn’t perfect for the track out of the box, but most cars aren’t.

Come into the turn slightly slower than you did in your Honda and get on the gas sooner in the 911. That rear weight bias gives better grip through the turn and on exit, but if you come in too hot with the light front end, it will be harder to get it to bite to where you can get on the gas. Once you have the front end sliding at tuen entry it will continue to push.
The wider front tires and other suggestions won't hurt either.
