I agree with the posters who say that if you do not disagree with Catholicism doctrinally, then you should not leave the Church. The reasons for the divisions between Catholicism and Protestantism are doctrinal, and if you actually believe in Catholicism, but are fed up with some of the goings on in the Catholic Church, you’re not going to be theological fed, in many regards, in a Protestant body. A high Church Anglican (Episcopalian) church would, of course, be very similar to Catholicism in terms of liturgy and down most of the line doctrinally, but if you truly are a [i[believing* Catholic, instead of just a cultural one, you’re not going to be in a place where you agree with the theology.
If you do agree with Catholic theology, but absolutely must leave the Church, I would suggest looking east to Orthodoxy before looking to Protestantism. Doctrinal differences would be comparatively minor, though the liturgy is even more liturgical than what you get in Catholicism.* Some Orthodox parishes in America can be very ethnic, but most are quite welcoming.

- Though if you want to stay Catholic, and like the Orthodox worship style, there are non-Roman Catholic parishes that are in communion with the Pope, such as the Byzantine Catholic Church, which are Catholic, but use Orthodox liturgical styles. The whole relationship gets beautifully complicated.
Beyond Orthodoxy or Anglicanism, you’re not going to find much else in the Christian sphere that would be both mostly doctrinally or mostly liturgically similar to Catholicism. You’d have to give up one or the other (Lutheranism is doctrinally different, but liturgically very much the same, for instance). Methodism, Baptist christianity, Presbyterianism, etc, would be even further far afield.
So I guess what I’m saying is what sort of Catholic you are determines your options. If you believe the Church’s teachings, like the liturgy, but are fed up with the leadership, I’d think you have little option but to hunker down, perhaps find a new Catholic parish in your city, and pray for the best (I’m sure the Church would appreciate Rosaries being said with prayers that the Church should right itself from its recent foibles).
If you can give up some doctrine and want the liturgy, look to Anglicanism, maybe Lutheranism. If you want something more doctrinally similar, but aren’t afraid of a very different, even more ornate, liturgical style, perhaps Orthodoxy would be your thing. YMMV.
Best of luck!
