So, I hesitate saying this, because I feel like I am the only person that has this opinion, but I think I at least have to share it. If others see this as completely messed up and wrong, then tare it to ribbons and I'll drop it

I see you as an Fe dom.
Maybe Te dom, but Fe dom stands out the strongest. You strike me as very Je. I can't see you an introvert. I honestly don't know how or why others are seeing you as a Pe dominant. You seem to be very "orderly". The way you present yourself is as someone who creates structure and frameworks to function under. There's a lot of certainty about you. Not so much with explicity declarative examples, but overall you have a very "this is how things are" vibe, and a lot of it is external. This is very Je. I actually relate quite a great deal to what you have written (some I word for word identify with). With myself, appear more like Te, and I'd argue that it's the first impression people get of me a lot of the time. First impression doesn't make it correct though. When I take MBTI tests, I almost always get ExTJ. The thing with Fe, it's not this fluffy pile of love. It's very concerned with external order, it just does it in a subjective manner. You seem very ok with doing that. Te is much more objective and very very separated from the self. If something can't be removed of objectivity then it doesn't want to touch it. You seem to apply a lot of "quality" to your decisions. The fact that you're an 8w7 sx/so will also make Fe appear much more gruff. Some might claim that Fe-8 is not possible. It absolutely is. It's not nearly as rare as the Te-2 conundrum.
You do seem very "at peace" though, and that is likely from a strong influence from your tertiary function (whether that is Ne or Se I am not sure). Despite the certainty and directiveness you put across, you're ok with it not always being there. Ultimately what seems to matter more is the end goal. How that's achieved is sort of irrelevant is the impression I get.
Really, I think you might be ENFJ, possibly ESFJ. Again, no one has suggested this so far so I am hesitant to give it, but nevertheless it stood out to me enough that I had to go with it.
