Namesake:
You said
“Catholics think they already have found truth.”
Actually, The Truth found us. And that Truth permeates our Church and our lives. He just does it on His time.
I teach in the RC program. Recently, I had a man who came through that program about four years ago come up to me after mass about a month ago and say, “I finally get it”. When I asked what he meant he said that he finally understood what I said in a class about the Eucharist and the real presence of Christ. We laughed about it, and being a cradle Catholic, I told him it took me about forty years.
At least in my little corner of the world, we don’t demand that anyone wishing to investigate and possibly come into the church, categorically believe everything all at once. We just ask that one “be open to the possibility”. It’s another way of saying that we recognize each individual’s unique understanding of truth, and that God works His will on His time.
I offer that if you’re looking for a Saul of Tarsus/Road to Damascus moment, you’ll probably be disappointed.
You also said that the Church isn’t always right. If you’re talking practice, you’ll find a lot of people who agree with you, right up to the top guy in Rome. If you are talking dogma, teaching authority, and core beliefs, understanding CC teaching takes some time. (and some patience with the people who teach it

) Good luck in finding what you seek.
Shalom
