Help me find my passaggio

So I've taken a few classical voice lessons with two different teachers, and for the time being there is no absolute opinion on what I am (voice type wise), which is fine.

However, neither of the teachers that I've seen tried to identify where my passaggio lies (at least they didn't tell me) - and I think I could benefit from getting some opinions on where it falls, because I've tried the various methods on the various subreddits, and they yielded varying results - which I won't specify here.

I know that this really is something best left up to a qualified voice teacher, and that just hearing a few sound clips probably won't give you a lot of information, but I would love to get some of your opinions anyway.

So I'm giving a few links to some recordings on SoundCloud - two are ascending-descending major scales starting on C3 and rising up as much as I could handle, one is roughly in speaking voice - and the other uses "operatic technique" (to the best of my ability at the moment), with more breath support.

The third recording is me singing "Vecchia zimmara senti" from La Boheme, nominally a bass aria - that could also be sung by any tenor; I went for it because it fits in the range that I'm comfortable singing in at the moment. I'd like to get an opinion on the timbre of that one, as well.

If anyone would go so far as to say, without specifying fach - if I work on my voice and it develops in the way you think it should/would - what role/s do you hear this voice sing eventually?

I would also like to make clear that I've only taken three lessons so far, so I do go off pitch in places and my breath support is terrible, as well as a thousand other problems probably - which is also fine at the moment.
