As for heresies, the Church does not condemn those people who are in “material heresy” - in other words, not knowing that the teachings that they profess are heretical. This includes most modern-day Protestants. This is why we don’t call modern-day Protestants “heretics” (even though their teachings are, according to the Catholic Church, heretical), but “separated brethren”. The idea is that most Protestants (including most Protestant pastors/ministers) are unaware that they have, according to the Church, been misled.
Most so-called “formal heretics”, btw (those who knowingly and obstinately professed beliefs that they knew were heretical), were clegy. Martin Luther was a Catholic priest (Augustinian order), Zwigli was a priest, and so was John Calvin. Arius was a priest, Pelagius was a bishop, etc.
Obviously, God would want you in the One True Church. If you’re interested and you can read at a sufficiently high level, read materials by the so-called Church Fathers describing the Church (btw, I’m not disparaging the education of the OP here - I tried reading Augustine once and struggled to get past the first page). These would have been written before even the Great Schism. As such, the only Church at the time would have been the Catholic Church.
And remember, until the 1500’s in the West (and until around 1100 in the entire world), the words “Catholic” and “Christian” were synonymous. It wasn’t until after the Reformation that Protestants started to claim that Catholics weren’t Christians. There is nothing that irks me more as a Catholic than a fallen-away Catholic saying “I used to be Catholic and now I’m Christian”. Or a Catholic saying “I’m not Christian, I’m Catholic”.
I am a proud to be Catholic - the fullest form of the Christian faith. Jesus is my personal Lord and Savior, but not just that - when I consume Jesus’s Body, Blood, Soul, and Divinity in the Sacrament of the Eucharist, I become His hands, His feet, His eyes, His ears, and His heart to the world. So do we all. We, the Church of God, become the mystical Body of Christ. We are the bride, He is the bridegroom. Our goal? To be Christ to the world, to preach His words, to perform His miracles, to bring the world to Him.
By the way, The Holy Sacrifice of the Mass is a form of time-travel into the Last Supper, Passion, Death, and Resurrection, where Jesus sacrificed Himself - we are actually present at the Last Supper, the Passion, Death, and Resurecction all at the same time (the “beloved disciple” in St. John’s gospel is not just St. John the apostle - the “beloved disciple” is the Church, the people of God)!
There are many reasons why to be Catholic. But, honestly, there are many misconceptions in the world about who we are, and it might take you a long time to clear these misconceptions. There are those who believe that we worship the devil (we don’t) or that the Pope is the anti-Christ (he isn’t). There are those that equate “praying to the saints” to mean “worshipping the saints” (we don’t worship the saints - we believe that they’re in Heaven and “praying to the saints” really means “asking the saints for their prayers”). We don’t worship our statues or painted icons.
And the Bible? We decided which Christian writings were divinely inspired and belonged in the New Testament - and which ones did not belong. The Bible itself does not say what belongs in the Bible (the Table of Contents is not part of the Bible), so the idea of sola scriptura primarily falls apart first and foremost on that point - it required Apostolic Tradition (and the magesterium) to determine what was Sacred Scripture in the first place. How can Protestant denominations claim that the Catholic Church had the authority to determine the contents of Sacred Scripture (which they imply by accepting what the Church had determined what was Sacred Scripture) yet think that the Church never had the authority to do proclaim anything else?
Just pray, and continue to learn more. Jesus is drawing you home, but it may be a long journey.
