Another resource might be the Unitarian Universalists. The UU, from what I have seen from friends, embraces a freethinking experience within a church-like community. It's a mix of the theists, agnostics, atheists, etc. The children's programming (Sunday school) explores various beliefs in a personal search for meaning. It's member-run so it really depends on your community whether the vibe fits you, but it might offer a space for discussion among peers, and people of different ages and backgrounds.
