My opinion is that denomination-connected congregations rather than non-denominational congregations are a wise place to start. Denominations provide additional resources and accountability that standalone congregations sometimes unrealistically expect one leader or one staff group with a strong personality or skill set to provide.
Our family, however, is part of a community church that's only informally connected through its worship culture, lay-council polity, and pastoral credentials to PCUSA/RCA/UCC.
If we were to join another church someday to have a denominational identity, my first look would be United Church of Christ. I have been very impressed with the denominational resources provided for lay people and leaders through this denomination.
www.ucc.org/ Their denominational history is the reverse of splintering . . actually started out as a combination of a couple denominations or faith traditions. They have a commitment to and tradition of multi-ethnic and multi-gender leadership, which to me is an important signal that pyramid-style authoritarianism or goodol'boys culture is not going to do its normal damage.
When I transferred out of my childhood PRC as a 20something, I became a member of a presbyterian church in Chicago because it was close to my new home and because it had excellent preaching, music, and adult faith/education/formation courses. When my family moved to northwest Indiana we joined a CRC church close to us and were members there from 2002-2017. Now we are members of a community church in the village we moved to in 2015. What I love in general is that never, not once, has any preacher in any of these churches spoken of other churches in a disparaging way, or set themselves up as a more favored flock of God than other flocks. Flee from churches like that, they are resting on competition and comparison dynamics like an insecure sibling who believes that parents have favorites based on offspring performance or earned-value. Some parents do love that way, but not the Parent we can cling to as part of our Christian faith
I totally affirm anybody taking a short or long break from church group settings to just find other topics for your brain to focus on, especially if trauma symptoms are triggered by going back into a church building.
I've been able to find healing and renewal in the congregations I've been a part of and while none have been constant rainbow and unicorn experiences, they've been full of great people, relational and spiritual discipleship that I've needed, and best of all, regular messages of the unconditional way that God loves and values each of God's creatures.
You are secure in God's approval, now you get to work out your own story of finding the ecclesial body system, limb, organ, or specialized part (hand, ear, eye, toe, lung) that connects well with your own gifts or needs. All are part of the re-ligamented organism of Christ's kingdom in this time of history! No place on earth is too far from the Holy Spirit's LifeBreath, if you connect with a few other humans who are also earnestly hoping to love and keep discovering where we've come from and where we are going.
