I just see a lot of people here saying that NFJs understand them better than anyone, and while my experience of NFJs is that they are understanding people ...they don't particularly get me more than anyone else. In fact, my ENFJ sister and I are quite close, but she doesn't get my Fi at all....she totally does not understand it.
Or on this forum, for example, I've watched an INFJ in action as she tries to understand other people...and it seems that she extends that courtesy to people she respects, in general.
My bff from high school is an ENFJ, I think, and she's very personable, and we have a deep connection, but we don't understand every single thing about each other.
Same thing with my ex...we were together five years, had a very deep connection...he's probably eSFP...but, again, we did not completely understand each other.
I even remember feeling a certain unspoken bond of understanding with my ISTJ grandfather sometimes, but he and I were outwardly about as different as day and night.
