Yes, you are in the correct zone for this particular apple tree.
It means you need a cold season. Not hot all year round.
Unfortunately I'm not sure if this is a dwarf variety. Fuji should indeed work as a pollinator!
Cortland, Empire, Fuji, Gala, Granny Smith, Macoun, Pink Lady, Suncrisp are some notable apple varieties that will work as pollinators- there are a ton of others if you look it up.
