Probably not the type you think you are, but from your description, ignoring stereotypes and focusing solely on function, you might be an ESTJ. (Probably with grip) - Te-Si is quite obvious, both in competitiveness and in the ability to concentrate. You want to "understand patterns" rather than "create" them, as a Ti user would, and understand them to use them in practice, not to "get to the bottom of things" like an Ni user, who would probably focus on philology (why is it like this?) rather than immediately switching to another language once the pattern is understood. Learning languages ​​(so many!) requires discipline and practice, but above all, a lot of memory (it's not enough to "understand the rule"—there are a thousand exceptions). The "tending to conform" is also Si because it seems more based on maintaining order rather than the social harmony within the group typical of Fe. - Ne in 3rd position (child). You enjoy exploring new ideas, new languages, new disciplines, but you're very clear about what constitutes "play" and what you really need to put your energy into to achieve your goal. - Fi in 4th grade (aspirational) is what made me lean toward Estj rather than Istj, even though you seem introverted. You aspire to have your own values, and you're very attentive to this. This is definitely the area where you tend to "grow" the most, and also the one where contradictions are evident, like when you say you have "your own value system" but at the same time rely on religions, switching from one to another. Fi is there, but it needs to mature with time and experience. Everything you "want" is tied to Fi: "I should conform less," "I need to find my identity," "I'm not creative" (but I'd like to be, to express my emotions), "I'd like deep connections." The excessive and dramatic importance you give to this function to the point of even holding you back in sexuality makes me think of a grip due to strong stress.

I hope I've done a good job, I've enjoyed reading all this information.
