Good thing is I'll always be ahead on knowledge of what you need because of our similar climate to yours.
Also I am remembering while doing research on nut trees in the past the nut trees with the more aggressive vegetation growth did better at high altitude, as a matter of fact some of the more aggressive nut trees die in some of the lowest elevations. So I am thinking that any heat loving fig tree that has very aggressive vegetation growth should do great in your location, also I think that a fig tree needs to be a high production one to do well at high elevation. Just like some people are too weak to hike a high elevation I think plants can be that way too, just like fig trees that are very tough can resist disease way better.
