You can take a train from basically any town in Fairfield (including new Canaan and Wilton as they have spurs that connect them to the metro north) and pretty much any town in Fairfield will all of your boxes excluding diversity (but that doesn’t mean they aren’t welcoming for all). It would help to understand why you are leaving nyc and what you hope to have here that you don’t have there as well to place a good fit better. I made the move couple years ago
