I think one of our lovely SJs @EJCC might be able to help you regarding relation to the temperaments and all.
FWIW, you don't seem as scatterbrained or tangential as EP types. I think your energy is more steady, smooth, and level-headed like J types. If you want to compare that EJ vs EP energy you can look at Chris Pine (ESFJ) vs Kelly Clarkson (ENFP):
Hmm, I don't know. On the other hand, I've left the question of my type open a lot longer than most J's would have, at least those I have observed. And have continued to consider and re-consider things at length, often coming to some possibilities randomly. And my tendency is to consider issues at this kind of length in many areas outside of 16 type. I can't see that coming from S or J, especially if they were both present. In my observation, J's become easily frustrated with continued questioning. They just want an answer and to be done with it. I don't know if those ideas about Js being more composed and level-headed are just stereotypes. I know plenty of Js who I consider temperamental and immature.
