What you describe is really familiar! I felt pretty much the same way starting out.
To begin with, my transition goals were "I want a more feminine body (specifically breasts)"; that was it. If it turned out I passed as a woman and people called me "she/her" that would be fine, but I'd probably stick with my old name and social role. Probably wasn't going to get bottom surgery or anything. I'd just be a dude who looks like a lady, to coin a phrase. Whatever nebulous essence of femininity cis women had, I didn't understand, and I didn't have it. I was just me.
What happened next though is I got on HRT, the body issues started to get resolved, and I realized that I wasn't actually OK with being seen or referred to as a man. So I changed my name, with a kind of "yeah, I know it's weird to have a girl's name, but that's what the documents say, so if you wouldn't mind..." approach. And I started presenting more and more traditionally feminine so that other people (and myself) would see me as a woman without prompting. I still felt that I was kind of faking it; I wasn't a "real" woman, just pretending to be one. (Oh, and I realized I really did want bottom surgery after all)
But now I've accepted that everyone is "just me", and I have just as much right to call myself a woman as anybody else. I choose to believe that deciding to be a woman is exactly what it means to be one! That's not to say that other viewpoints are necessarily wrong, but it's the only interpretation that makes sense to me now.
So I think what I wanted to say is: I think how you are feeling is pretty normal actually, and it's possible your feelings will change as you get more comfortable with yourself. But it's cool if they don't.
Good for you!
I've been having more and more moments as well where I just stop and think, "this is awesome".
