And as you note, archaeological and historical records to support and verify many biblical writings. Not all biblical questions & claims have already been proven or shown to be credible of course, but but many of them have, as you noted supporting evidence for one part tends to lend credence to the rest. I suppose the question would be “what is an acceptable preponderance of that evidence, before accepting the Bible as true?”
In fact, things like these tend to discredit the accusation of “circular reasoning” that is often employed to discredit bot the Church & the Bible.
Ultimately, circular reasoning cannot be completely avoided in arguing for the ultimate criterion of any system. This is what Aristotle and St. Thomas Aquinas meant by saying that first principles are indemonstrable.
Nonetheless, the Church’s interpretation of the Bible or its inerrancy is not closed off from history or from scientific evidence.
There are no contraditions. When there appears to be one (or more), it is/they are typically due to my (our?) misunderstanding.
Not exactly. The Bible doesn’t explicitly condemn or support either, which is why we are free to “pick & choose” what we believe in this area.
LOL.

I thought so too, many years ago.
I left the church when I was your age too. Not for all of the same reasons, but I also “realized” that neither the bible nor the church “had to be true.”
It was the beginning of a new, simple freedom, where I didn’t have to worry about how I acted; where I didn’t have to “accept” what I thought were contradictions.
“Everyone was just complicating everything with all this stuff!” I thought.
By simply considering the Bible/Church to be “wrong”, I could just disregard it all, live simply & not worry about all the things that they said that I didn’t believe or understand.
Some years later, for some reason, I revisited some of the “problems” I had with the Bible itself. After looking at all the evidence lending credibility to the Bible, I came to return to Christianity, although I still had trouble accepting what the Catholic Church taught (like contraception, authority, infallibility, etc.)
Not too long ago, I ended up looking at those “problems” I had with Catholicism in the same way as with the Bible, & I came to see that Catholic teaching didn’t contradict the Bible, and like the Bible, was supported by outside evidence, like the aforementioned archaeological & historic evidence, so I “came home” to the Catholic Church.
You are, of course, free to take whatever course you desire, but I would encourage you to actually list the specific items you have problems with, and look to see what evidence (for or against) is out there concerning it.
