Best cold-hardy variety for permanently-outside container in mid-Atlantic 7B?

Howdy! I live in Baltimore and I don't have any in-ground dirt to grow in. I do have large trough containers on my deck (36 inches long, 15" wide x 15" tall). What varieties, if any, could I plant in the containers and not have to bring inside every winter? Happy to prune and do root trims yearly. I know I will be gambling with die-back, especially after this past winter, but the fig shuffle in and out of the garage this spring drove me absolutely crazy.

Would Ronde de Bordeaux, Campaniere, or Michurinska 10 work? If I can, I would like to try something other than Chicago Hardy or Brown Turkey.
