It certainly can be confusing. They don't call Presbyterians "Split-P's" for nothing. And that's not counting the variety of Dutch Reformed denominations and various Calvinistic Baptist groups.
What direction to go depends on if you are looking for something evangelical/conservative or if you are looking for something more liberal or mainline. I haven't been active here in a long time, but I've seen some of your recent posts. Based on that, I would think that you are probably looking for something on the conservative end of the spectrum. It also depends on if you believe in infant baptism or if you are baptistic. (Many Presbyterian churches will allow you to join even if you don't agree with infant baptism, so long as you aren't divisive about it.)
Most of the confessional (i.e. subscribing to the Westminster Confession of Faith or the Three Forms of Unity) Presbyterian and Reformed denominations are part of
NAPARC. That site should have links to all of the denominational websites. From there you can search for churches in your area. Some of these denominations would be very conservative when it comes to worship and not associating closely with non-Reformed churches, and others like the PCA are more broadly evangelical in outlook. There can be quite a bit of variation in the PCA especially.
The Evangelical Presbyterian Church (EPC) isn't part of NAPARC because they allow women to be ordained. But they are generally conservative compared to the PCUSA. Some of their congregations have women officers and some don't. They also are more accepting of charismaticism than are other conservative Presbyterian and Reformed churches, many of which are strongly cessationist. Many former PCUSA congregations joined the EPC when the PCUSA moved toward acceptance of same-sex marriage.
The Christian Reformed Church (CRCNA) used to be very conservative but it had to leave NAPARC a few decades ago over their choice to ordain women. They have moved "leftward" on some other issues too, if I'm not mistaken. The other large historical Dutch Reformed denomination is the Reformed Church in America (RCA.) It is a mainline church similar to the PCUSA and others. The CRCNA used to be considered much more conservative than the RCA but from what I understand, they are not as far apart on some issues as they used to be.
The main difference between Reformed Baptists and conservative confessional Presbyterians is their views on baptism and church government. Some Reformed Baptists are part of a denomination like the Southern Baptist Convention, some are part of a smaller association, and some are independent.
