Your area seems to have many moths with the average lows in the 40s as well as only a handful of months in the mid 80s or better. With taht being said, and since you want to grow it in the ground, your best bet is keeping it maintained at a smaller size, the Richard Campbell method (which is not a bad idea for anyone). This would allow for you to keep it covered and protected during extended cool/cold periods.
Now, as to variety...if keeping it pruned and smaller, I would pick a tree based on taste. Having a jackfruit tree just to say you do that produces average quality fruit at best is not worth it, ay least to me, With that being said, I would go with Mai 1 or Mai 2 (Mai 2 should give you a "smaller"/more compact tree but also POSSIBLY not as precocious as the Mai 1.
