It's probably easiest for me to contrast myself with my nfj so/sx friend, who wears herself thin and has always had the most incredible network of friends and acquaintances, and tends to be involved in a lot and is always busy. In some ways I am in awe of her, just... how does she do that? How does she flit around so easily? How does she know so many people? Of course behind the scenes, I know that she doesn't really connect well with many, but still, she's a good contrast with me because she's heavily involved in so much.
She also succinctly described me once as being 'tactful but direct'. I think this directly ties into Fe (the tactful/diplomatic part, i.e. valuing mode of communication and being very aware of the audience), but I think I'm more direct than many FJ's as well. So I think it's that I value being aware of my audience and perhaps prioritizing their communication/interests/quirks over mine, to facillitate communication, but I am also willing to break the peace and introduce an awkward moment if I feel something needs to be said, or I may not care in certain instances how it will reflect upon me if I say something (or maybe more accurately, I am aware of how it may be viewed, but I am willing to accept that result).
Myself? I'm an uber-hermit in comparison to her, and I tend not to be involved in anything, nor do I really want to be involved in anything, tbh. It's a weird conundrum, as I greatly desire close relationships, and to actually be in a position to meet people means I actually need to get out and do something, and get 'involved' in something, some sort of group, whereby I then have the opportunity to possibly meet like-minded people, but I have no core desire to join a group, start doing group/team activities, etc, so I then tend not to meet people. lol. This has been unchanging my entire life- just a strong distaste for being 'involved' in anything, being a part of a larger group. The only reason I'd join a group is to possibly meet someone I want to be a close friend with, and then do 1:1 stuff with them on the side, and then cease to do the group thing. So the whole thing is just a problem for me.
I guess you could say that the so - group-harmony element isn't really applicable to me because in my free time I prefer not to even be part of a group?
Similarly, at work, I have always tended to be pretty outspoken ->in a diplomatic, unbrash sense, but I still let my thoughts be known. Funnily enough, in a review several months ago (and I think this ties into the so-last thing), my boss told me that one of the things I could work on is being more PC in meetings and not letting any exasperation or frustration be displayed - basically, the gist of all of it is him wanting me to put on the PC-happy face more often, and work towards being more 'part of the company' than setting myself back from it. It was an interesting thing to hear. [I should also note my so/sx friend is far more apt to put on a happy face and say the pleasantries than I am]
On the other hand, in reviews I tend to be rated above expecations for customer service stuff, so I think that ties into knowing my 'audience', knowing who I'm working with, and being able to build those positive 1:1 relationships.
In summary, I think while I may be aware of group dynamics, and what the larger 'Group'/entity is all about, and how I would need to be to totally merge with that group, I just have no desire to do that, and so I then don't really identify myself with any groups/causes, as it's not my concern. But within the group, I focus 1:1 with people, and the Fe comes into play with tailoring communication (more applicable at work) and building those 1:1 relationships. My awareness of 'the group' may help in knowing how to most effectively accomplish something, but I don't really care about identifying myself with the group or keeping the peace.
