"personal relationship" with God

This for me is the most important thing. Life is in the eye of the beholder. We all have different ways to experience it.

but I’m still wary of exposing them to obviously harmful ideologies before they’ve developed the cognitive fortitude to withstand the psychological and emotional assaults of charismatic bigots.

It makes my heart sing to see this. I think that you can join in with the new church and simply enjoy the spirit of community is awesome. If they can accept that your beliefs wont always fall in line with theirs then it sounds like you have found a very thoughtful bunch of people to hang out with. I agree with caution and think it was brave of you to take your daughter along, but also think it was the right thing to do.
