Welcome: Unitarian Universalist Society of Sacramento
Because I really liked Scott McClellan's book "Finding Your Religion" and he was a Unitarian Minister, I thought I would give it a try.

Theologically, the Unitarians probably are exactly what you are looking for. You have a lot of people attending who aren't sure if there is a deity or people who are mostly interested in being spiritual. In terms of theology I thought some of it had some potential.
That said in practice, I really didn't care for it. It seemed more like a meet up group for the local chapter of the green party than an actual religion. There were a lot of people who had different ideas of what pursuing social justice meant. Often times it seemed like people calling on some abstract higher power to do the will of Ralph Nader. I wanted to like this place and you might like it yourself. But it wasn't for me.
Because I really like running the Spritual Path, which was also really good, I spent some time attending the services at Trinity Cathedral. In terms of the services, Trinity Catherdral was probably a better fit than the Unitarians. There were mentions of God and I liked more about how open the members of the Church will actually willing to discuss things.

At the moment, I am attending the Latin Mass at professed by the St Pius Society. In terms of theology, its probably the furtherest from what you are looking for or really what I thought I was looking for. Yes its the group that had the bishop who denied the Holocaust. But in terms of ethetics, its tough to beat. The men wear suits and ties, the women and girls wear vails over their head. Most of the service is in Latin and the parts of the sermons that are in English are mostly over obscure issues of faith. There is lots of stained glass and most of the statutes of God show him in agony.The services are communal but highly personal. People are in the same room saying some of the responses together, but there is no sharing with other people at all. I find actually prefered the sermons about obscure articles of faith because then you had the time to think about the things that matter most to you in the service. I also liked that there are so many people showing up before services to say the Rosary and their genuine sincere belief in a Diety. Is there a God, I don't know, but in terms of services, I have found I like the ones that seem most commited in their belief that there is.
For me, right now, its the best fit, but I doubt that its what you are looking for.
