Why did I become a Catholic?
I became a Christian at about 14 years old. When I first heard the gospel, thought “If this is true, I want in! But how could anyone know if it is true?”, and then I thought “If I accept it tentatively, sooner or later the truth or error of it will come out.” So I did, I got baptized, and over the next number of years, I studied, learned, questioned, challenged, doubted, and even rebelled. Eventually, I came to where I could not honestly deny it. During that time I did learn some about the Catholic Church, my main question was do they hold the same core beliefs about how one comes to be saved? Namely is one saved through faith in Jesus Christ through GOD’s grace, and expressed through repentance and good works? (Note that the Catholic Church states that salvation is expressed via good works not established by it, good works being a fruit of salvation.) I found that they did. At that time I left the issue as indicating that the Catholic Church was another of the legitimate Christian denominations. Then, to be brief, I married a Catholic. After years of attending Catholic church, and learning from my Catholic wife, I decided to join the Catholic Church. This would be the first denomination that I joined. I had always been a non-denominational christian. Below are the main issues that were involved in my decision.

Regulation vs individualism
On one hand, any governing body governmental, business, or religious, will make new regulations, after all, their purpose is to add regulations. But they tend to come to the point where they over-regulate. The Catholic Church is not an exception. Some have left it due to this.

On the other hand, the sheer number of denominations that claim to be Christian, over 200 in the US, and 45,000 worldwide seems to point to a logical conclusion of each person making up their own beliefs.
I think the former, while imperfect, is preferable.

Scandals
With this issue the Catholic Church certainly could and should do better than it has. Having said that, this issue plagues every organization that regularly places people together, especially the innocent and adults; clubs, schools, churches, businesses, all of them, sometimes have this problem, and no less often than the Catholic Church, as Michael Medved, American radio show host, author, political commentator, and film critic, said. Also the Catholic Church is the largest and oldest organization there is, making it an easy target to find fault with.
It is a human problem, not just a church problem.

Satan hates the Catholic Church
Today, Christianity generally, and the Catholic Church especially, is the one religion that one can mock and hate, it is without protection from political correctness. This seems to me to be an indication that the Catholic Church is the supreme denomination.

Proximity to Christ
There is no denomination, no religion, faith, or way that originated closer to Jesus Christ. As I discuss here. This proximity is unmatched in ancient literature and historical records. Further, JESUS did say “Now I say to you that you are Peter (which means ‘rock’),[b] and upon this rock I will build my church, and all the powers of hell will not conquer it. And I will give you the keys of the Kingdom of Heaven. Whatever you forbid[d] on earth will be forbidden in heaven, and whatever you permit on earth will be permitted in heaven.” Matthew 16:17-19 NLT. He did not say it would not be besieged, conflicted, damaged, or attacked.

Miracles
Recently I realized that It is what is called a year of Jubilee, a special year of forgiveness, reconciliation, and renewal. I mention this as an example of a phenomenon that involves the opening of doors and, variety of small but poignant events and circumstances have played out that make me feel that something mysterious is pointing me in this direction. Things that to tell them would not seem particularly significant, but which form a conversation. The further I follow this path the more I feel that it is the right one. I am joining the Catholic Church in the year of Jubilee.

Christian/Catholic relations
I want to say here that currently Christian/Catholic relations is a travesty.
For example:
Contrary to the common understanding if the Catholic Church’s position, according to Catholic teaching, we are not to worship any of the icons or symbols used by the Catholic Church, we are to see them as reminders of Christ and what HE has done for us. Otherwise it could be inferred that any art could be called blasphemy, which it is not, unless one does worship the art.
Too many Catholics say that many non-Catholics, those that hold the view called “Sola Scriptura”, scripture alone, do not allow for the HOLY SPIRIT, tradition, etc. But actually many non-Catholic Churches teach “Prima scriptura”, the doctrine that scripture is primary, "above all other" sources of divine revelation, such as the Holy Spirit. This being little more than a somewhat different balance, but with the scripture being higher authority than the Church where they in contradiction.

The Catholic Church and wider Christian world should recognize when they agree on how one is redeemed, and, when their other beliefs are not blasphemous, and focus on redemption rather than argue over secondary and tertiary beliefs.

The only thing that really matters is salvation itself.
