First time visiting Oregon as a family

We have three young kids (7,5,2) and are trying to plan a late July/early August trip to the coast. We’re looking to rent a home for a week and I’m wondering what a good town to look at renting in for a family would be? I’ve heard Manzanita is wonderful, any other places with good beaches, tide pools and lots of kid friendly dining options? Bonus if it’s not overly crowded.
