Walnut Creek, Lafayette, or Moraga Elementary Schools?

Hi all, I’m looking for advice on what the biggest social or educational differences might be at the elementary schools in Walnut Creek, Lafayette, and Moraga. 

We’re a mixed-race family and I want to set them up for success both academically and relationally since it’s a key time for social development. 

From what I’ve read, Moraga and Lafayette seem similar academically and the main difference is programs like music, sports, etc. because of parent fundraising—has that been your experience? If so, I'm wondering how Walnut Creek compares. 

Culturally and socially, is there a district that is going to generally feel more diverse and inclusive? I'm a black parent who really wants to get involved and build my own relationships with parents so hoping to hear feedback with this in mind as well. Also, if anyone has any helpful suggestions on how to tackle this as a newcomer, I'd love to hear them. 

Thanks in advance!
