Hey Aaron, just catching up to this thread. For perspective I learned golf as an adult and I'm around a 7 right now, somewhere in the archives I have one or two similar threads to this one in this forum.
You are getting so much conflicting or just random info that isn't necessarily wrong but you just can't take all of it and implement it. Your head is going to be full of 100 things every time you try to take a swing and every bad shot is going to be analyzed 100 ways and it's unrealistic.
If you want to watch YouTube videos I would suggest pick one prominent guy and just watch and follow all his stuff and ignore everything else. I am partial to Monte scheinblum but there are Plenty of guys putting out good quality info. But you can't just take a piece here and a piece there from different philosophies.
You are so athletic I think you need to just make sure your basic setup is textbook and it will put you in a good position to use your natural talent. All you can really control consciously in the swing is the setup and backswing. Once you get anywhere near the top you *maybe* can have a swing thought for transition but your brain is going to say "I gotta hit this ball" and you have good hand eye coordination so it's gonna do whatever it needs to do to make contact.
Your setup is quite good maybe slightly too much knee bend. You simply have to do some mirror work or drills to fix your takeaway and early backswing though. You will never cure your loop until you reverse it. Over exaggerate the other way. The clubhead has to stay outside your hands. Eliminate the wrist roll, these are things you can control. Your current swing is drawing dead to be great before you are even halfway back. Your natural athleticism saves it but you will never be great that way. Fix the basics. Exaggerate a steep backswing and on video it will still probably be too far inside. When you try to change something what feels like two feet will be one inch on video.
Good luck let me know if you ever get down to arizona
