I definitely agree with the tritype. I had actually guessed that before I checked what you actually typed as.
And since nobody did Cellmold, I might as well do it:
I'd guess ISFJ or maybe ESTJ going by what I've seen. Your posts seem to be generally quite short, which suggests you either think things through before posting or you judge yourself preemptively and don't post much. Or, I suppose, you're busy doing real life stuff, in which case ESFJ would make a lot of sense.
Whoever is beneath me can do CAPTAIN_INVINCIBLE (in whichever fashion he finds most pleasurable) and skip me. It's a combination of those suggestions, although I can't defend myself using "real life stuffs" since I really don't have much of a stereotypical life; yknow parties and people...people, stuffs, weddings, romance, sex, parties, people...people...and people. At the moment I'm working a lot, but that's just noise for money which is for general security.
I used to be far more expansive in my older posts and created long, meandering messes which accurately reflect how my brain normally functions. But as I've been 'obligated' to go out and work for a living (more precisely forced by the system I was born into) I've found myself working more towards philosophies that can more actively help me syphon off, or resolve, unhelpful overloaded thoughts based usually in negative emotion and allow me to focus more on present moments in time. Not necessarily for work-based practicalities as mechanisms for dealing with my neuroticism, which I think I've made decent headway on, but there is always the potential for relapsing backwards. That's the problem in fiction (which I love more than reality in many ways because characters can only be the unadulterated sculpting of the author as opposed to the thin personas of 'real people') where a character goes through some trauma or series of challenges and slowly grows to meet the challenge, or fail, and then moves past it.
This happens in real life of course, but I think people can fall back into bad habits of thought and behaviour. Although that does make it look like they didn't learn in the first place. Might just be my reflection of how I experience it though. It could be put to type depending on how much stock you put in it, but I find more regularly that I openly see myself as this....just this form that's made up of everything else and only thinks it's thinking until it deconstructs. So I may as well have some enjoyment because at the emotional centre that decides the actual behaviour through sub or unconscious belief, it's hard to rationalise why I shouldn't and that it's very much some form of decision to do so as opposed to an entirely external power giving me some sentience or license.

Truely, I don't believe you're an SFJ, 6w7 seems alright
You're an INFx, you could be either. I know you have high Ne,Fi,Ni and Fe, so pick whatever you feel more comfortable with. I know you have considered changing your type to INFJ before, which is cool. I would actually bets fit type you as, INFx, since you could represent a healthy version of either, in terms of Cognitive Functions/ Behaviours. As for your enneagram, triple withdrawn seems reasonable to me. You seem like a reflective person, who knows what they want from life, and when to jump into things.
For those of you to follow me, simply pretend as though I never interrupted the flow here. Captain_Invincible, you're still up. I just need to fix my post about Cellmold in light of this new information.
After reading your post, it seems like both your Si and Ti are pretty strong. While both are present in ESFJ, Ti and Si are both stronger in INFJ. Of course, I could be mistaken, but now I'm leaning even more towards INFJ than I was previously.
(Sorry Cap, but you've already heard my thoughts on your type.)
EDIT: as themightyfetus points out below, I meant ISFJ. I didn't change it here so his correction actually makes sense.
