First timers to Cape Cod

Hey all!

My wife and I are planning to visit Cape Cod in September (9/6-9/13) this year with our 4 year old and 2 year old kids. As first timers where should we stay? Budget doesn’t really matter I just want to stay in an area that we can get to other towns easily or at least the ones we need to visit. Chatham? Brewster? Orleans? Dennis?

Activities with the kids, good food/drink, and “cute shopping towns” per my wife are the main priorities.

Beaches are an add on of course but I think that comes with Cape Cod in general. Any recommendations for towns to stay, food, etc very much appreciated!
