You're not blunt, but you're live and let live, you're honest and straightforward. That's the root of bluntness. And it's definitely not Fe-ish.
I don't see how your description demonstrates Ti. You get/do what gets the job done, that only makes sense and that is perfectly reasonable Ni-Te behavior.
Ti is less practical, deeper, less action-oriented. Remember, it's like Fi, but without value judgments. You can't have both Fi and Ti, the stuff you're attributing to Fi is either being done by Fi or Ti and I'm pretty sure it's the former.
But the functions are whatevs. Don't focus on them too much, you'll lose sight of the question you're even answering here. Basically... you don't seem like an INFP, do you seem like an INFJ? Not imo. You're chill and thoughtful, you value concrete, deeper connections with people, you're an individualist, live and let live, no-nonsense, no fluff. Not much Fe.
Okay, that's my thoughts on that....
You know what? I had sort of the opposite thing happen in my type journey. I used to think I was INTP before I knew much about MBTI, and often tested INTP. I eventually realized I was INFJ when I stepped back and said honestly, wait, am I anything like an INTP?
Ni is tricky. You don't feel its presence, it's a perceiving, and really more of a facilitating function than anything. You have to feed it, y'know, break it in a lot to really notice it at all. But as you get older, you get more efficient, you bridge gaps and extrapolate from all these random things you've done, you become more efficient at almost everything you do and you also gain a kind of focus, even ambition.
And the 2nd function is a slightly weaker extroverted function... the one you're really gonna feel and notice is that third function. Ti for me and, imo, Fi for you. Especially because it's kind of crude... so you could feel like an INFP and I could feel like an INTP.
Anyway, think about it, yeah?
Remember that your type is an effort to describe you, not the other way around. It doesn't have to be a perfect fit or anything, just sort of a compass.
