As someone who is not ENFJ, can someone here teach me abt ENFJ? Just a rundown with the cognitive functions + how their functions might show in their behaviors

I'm pretty sure I'm ISTP, but I act like totally different person when I'm energized and surrounded by my closest friends (a LOT of the time bc I'm in school). I don't know if I need to explain every detail, but basically idk if I'm ESTP or ISTP.
Can anyone give me some clear distinguishing things between the two? Or just some education
