Bananas dont seem to get too upset about things once well-established. Any pioneer species will do good on poor soils, like Ice Cream Bean's, Strawberry tree/Jamaican cherry, mulberries. Establishing a nitrogen-fixer will go a long way.
Can also consider dragonfruit, pineapples, papayas. Ive seen loquats and longans neglected by growers in S FL and they seem to do fine, though fruit quality is likely poor.
Once you establish some shade or if you already have, you could probably start some passionvines and granadilla. Any wet or overly saturated areas can probably start some pond apple to use as future rootstock.
