I would also look at Tenafly. This town would be a bit closer to Ridgefield and NYC. If you work in Manhattan, you can take an Express NJ transit bus, as there are many stops through the town and it would also suit your husband's commute. You'd also be neighbors to one of the most affluent towns in America, Alpine,NJ.
I don't know much about Ridgefield Park, but it's near Ridgefield and I know you don't have kids but it was voted "Best place to raise kids in NJ"
Runner-up in businessweek was Bergenfield neighbor to Tenafly, you'd save a bit more money in rent in this town. You can also take an Express NJ transit bus to NYC as there are many stops along Washington Ave in this town and would suit your husband's commute as well. Dumont and Haworth might also be worth a look.
I would also look into Oradell and Cresskill. Oradell is a nice town but is also closer to Paramus, where traffic might be a problem. Commuting from Cresskill to NYC and Ridgefield would be closer than Oradell.
