This immediately made me think of the book "blink" again, where you know something to be true but don't always know why you know it.
although I might ask 2 questions here... first being what are the results you are looking for, and then second could be whether or not they are hit, right? (cutting, bulking, strength, etc since this game of iron tends to have many different end goals)
Kleen got me hooked on ADF a while back. I think it was May of 2023 or so. I enjoyed surplus eating on lifting days and then followed with a minimum of 1 day (30hr) if not 2 day (60hr) fasts. I dropped I think 10lbs that month but IIRC also set PR's on Deads and/or Bench. It's just my personal anecdotal information, but an interesting experience! I'm no pro, but I've been under the barbell in one way or another for 25 years so that progress was not on an untrained specimen per se.
I am a bit behind here but I will try to address the thoughts I initiated.

My main point here is at some point, your may have to choose between what it takes to achieve an outcome and enjoyment of the process itself. The general goal is to find the best way to make the process as enjoyable as possible to achieve the desired outcome, but sometimes, that is not possible and there must be trade offs. In the game of lifting, the more advanced you become, the less these two vectors may overlap.
Some examples are:
A) The more muscle you have, the harder it becomes to build more muscle, so the wiggle room to do things less optimally to build muscle and progress becomes less.
B) The stronger you become, the harder it is to become stronger, so again the wiggle room to do things less optimally to get stronger and progress becomes less.
So its possible that in the past, you had enough room to make progress, that you could do things less optimally while providing enough of a stimulus to make progress. The less optimal things you were doing may make the overall process more enjoyable, so adherence and enjoyment were high. If enjoyment and adherence are top priorities while still trying to make some progress, then this is great. However, if the goal outcome of progress is the main priority, then we sometimes to recognize that some things are less optimal than others. Additionally, as your progress, you may have to do things do not particularly enjoy to make more progress. At this crossroad you then either have the option of accepting you are leaving gains on the table to keep adherence and enjoyment high, or you need to do the things you do not enjoy doing to make more progress.

Being under a barbell means little, I do not say this to discredit your lifting history or current status. I can tell based on your log and numbers that pure optimized strength training is not something you have years and years of experience with in the big 3. So to me, this means you still have quite a bit of progress you can make in this regard, this means you can do something less optimally, such as ADF, and still make great progress, which, if you like ADF, and you are not trying to maximize strength gains, this is a perfect scenario of appropriate trade offs.
I do want to put the IF review a shared into more context. If people with a lot less training experience, thus a lot more room to make progress while doing things less optimally had pretty subpar muscle building results with ADF in a controlled weight loss study then I would not expect better results for more trained people. So far, as far as IF variations that have been studies, the 16/8 seems to the most viable for more trained people without some serious structural and timing considerations.
