I would plant all of them and you will be able to remove what you do not like later. Not sure about Coconut cream as it is more difficult to manage and not very productive. Many others are smaller trees. I like Diamond River longan as it produces a lot of fruits every year no matter what you do with the tree (not the biggest fruits) but you can keep the tree on a smaller side. Emperor lychee you can keep dwarf, I have removed Muritius as I do not like it. Brewster is okay, you can keep it smaller, Sweatheart is the best tasting, but I already forgot when it fruited last time (on a list ready for removal). Jackfruit possibly will not fruit well in Tampa. Jackfruit (hates chill hours) or Lychee (needs chill hours), if one is going to fruit well, the other may not. Excalibur Red is not red. I have one super productive Cristela Red (not red) from Excalibur and I'm having too many delicious jacfruits, unless you want to eat jackfruits every day. Pickering, Carrie (if you like sweet tart), Mahachanok, Orange Sherbet, Coc - big yes! Smaller trees must face south. Buy arlo or similar one or two visible cameras and forget about fruit thieves. Yes, when tree is young you can amend it with top soil and compost just do not overdo on mangoes. You can also add 1-3lb/tree of earthworm castings and I would not add synthetic fertilizers. I have visited many Dr. Richard Campbell (mango genius) lectures, went to Fairchild farm not once. My opinion is slightly different, you need to give nutrients to your mango trees, especially when trees are young, trees are more resistant to all diseases then. You can also give synthetic fertilizers, but much much less than you may want. You can save any tree with compost tea from many diseases. Mango trees need your help, but not high N-P-K - those fertilizers are killing and never fish fertilizer for a mango tree.
