Since you asked, these would be the mango trees I would have in my yard:
1. Rosigold for ultra early season mango
2. Pickering or M4(productivity?) or sugar loaf(productivity?) for coconut flavor mango. (Pickering get watered down flavor with rain) Coco cream doesn't produce well for me.
3. Carrie - just one of the best flavored mangoes ever- but you should try it first.
4. Lemon zest or Orange sherbet (OS supposed to be more disease resistant) - for citrus flavored mango
5. Sweet Tart - in a league all its own
6. Maha Chanok for productive asian type mango.
7. Fruit punch - for fruit flavored mango.
And I think Keitt is the best late season mango out there with traditional flavor. These should give you something to think about but try them first if you have the opportunity. No one ever really agrees on the best mango

There used to be a thread on the mango GOAT...I believe lemon zest and sweet tart were the top two contenders at the time.
