Ooh, hadn't considered Black Sapote, don't have any experience with them, do they tolerate wind fairly well?
Ackee is a pretty tree, but I don't have much interest in the fruit.
Yes, still considering a Mango potentially, but not so sure about the wind and then would need to be sure I pick a Mango that is vigorous enough to shade the area, but not so vigorous as to be a 40' tree ready to fall on the house. I have a couple tiny mango trees growing in the backyard, so not much experience in pruning/managing them yet.
