It’s curious those religions in particular spoke to you – it is precisely those churches that have legitimate Apostolic succession (their bishops can trace themselves back through an unbroken line all the way to back atleast one of Christ’s Apostles) and valid sacraments.
Yeah that’s why those were special to me. I start looking at every religion from it’s source. That’s why I can’t be a protestant.
Which parts of Catholicism do you have reservations about? Perhaps you can start threads on those parts and have questions answered. Have you also investigated the Eastern Catholic Churches?
Do I have to dwell on them all here?

I want Francis to act more like the euccumenical bishop, a primus interpares unlike a despote which previous popes sometimes seemed.
I’m more in favour of Ecclesical Divore instead of Anulled marriage.
I have trouble with some Maryan theology.
The pope’s infallabillity should IMO only be used after a council of many bishops is in agreement. (not a big fan of papal infallabillity but I’m willing to let it pass)
I think females could possibly be deacons. That there is no female diaconate is tradition instead of faith. (as the way I see it)
More possibillities of wider and more diverse cardinals. Cardinals shouldn’t be excluded to bishops, theologian laity male and female should be able to become cardinals.
Harder position against abortion, but more compassion for anticonception.
Diversify christianity. Zaire rite, Anglican rite, Hebrew rite should and could be their own rites in their own way.
Priestly celibacy I would like to see in the same way the Eastern Orthodox do it.
(the archbishop of a specific region should be allowed to decide if there can be married priests in his district)
More seeking union with Orthodoxy and Church of the East.
Less seeking unions with Lutherans and Anglicans.
More focus on the diaconate.
Some might seem unorthodox to some catholics, but please respond to them in a kind manner. I have gotten different responses on this forum.
Yeah, I have investigated the diffent rites of catholicism, but I knew little of them except that they existed.
I’m not inclided to become Eastern Catholic as there’s almost no Eastern Catholics here in my country and I just as happily would turn Latin rite Catholic.
