Best stroller wagon for toddler and infant?

We are expecting baby #2 this fall and I think the best option for our lifestyle would be a stroller wagon instead of a double stroller. Im looking for something that can fit a Chicco car seat and my toddler. Bonus points if the floor can go flat for a nap (maybe I’m too hopeful). This would primarily be used for family trips to the zoo, lake, downtown event, or stroll around the neighborhood. Open to other suggestions if there’s something you love!
