Why would you ask a question of such gravity on this site and expect insightful or intelligent answers? Ask you nearest priest or do research yourself unironically. This is a not an intellectually oriented site. Don't expect answers that aren't shitposts or blantantly uniformed bullshit.
That being said, if you are really serious about being Catholic, then the best reason for it is that it unironically is the most historically accurate version of Christianity that's also not bound to any particular ethnicity or race. There's a book called the 4 Witnesses: The Early Church in Her Own Words and it goes over pretty much all the dogmas of the Early Church and how they are fundamentally unchanged from the times of the early Church. Which makes sense becuase Protestantism is and always was an overreaction to the corruption of the Church of the 1500s (which was real and denying it is kinda retarded), which made efforts that would have been better used to reform the corruption in the Church into splinter religious groups that preach something entirely different with very little to no historical basis in Tradition. This is where the general tendency of these groups to be ignorant of the medival period, the late and middle Roman Empire and the various tendencies and beliefs within the Church come from which is funny because dogmas like the Trinity and the Divinity of Christ were formalized within this period. It's generally good to be on top of your history, especially in some area where it is important to you on a personal or technical level.
Orthodoxy is fine, my only problem with it is that it tends to be extremely ethnocentric. If you are outsider in Orthodoxy, you will never truly be like the rest of your congregation since you don't share the ethnic or linguistic history with everyone else, which can be a bit alienating. Sure there is the Antiochian Rite, but those aren't common churches in the West IIRC. I'd rather not deal with that.
As for Pope Francis, unironically I don't think he's the greatest Pope ever but there have been bad Popes before him and probably after him. He's not all that special really. At least he's orthodox in his beliefs if generally ineffective.
Also for the trad Catholic thing, don't. If you are going to become Catholic, just go to Mass (even traditional Latin Mass or any other of the more historied liturgies), obey the Church and Savred Tradition and recive the sacraments. Don't do this trad/lib/Tex-Mex etc. Catholic. That's kind of an arbitrary distinction where there needs to be none. Also, if you don't want to be Catholic at the end of the day, that's fine too. Just make an informed decision and don't trust random shitposters for actual answers.
Catholicism is retarded and is more about ritual than the Bible. I don't know why right wingers are thinking that being Catholic is cool either when most DNC politicians are Catholic. There's a reason behind that.
Because the people in the DNC that are Catholic come from traditionally working class, Catholic ethnic groups that moved to America like the Irish, Italians, various Hispanic groups, etc. Now, they are basically the equivalient of cafeteria Protestants, that are culturally Protestant but don't care much about their religion. That's the same reson why the GOP is full of Christians that love Jews and Israel now even though that level of love for Israel is not only not in the Bible but actively unChristian: no politician is actually religious and uses their religion for brownie points. Or very few of them are.
