Well, with citrus I go to places like UCR: Citrus Variety Collection and Citrus Pages and they go into detail about the history of the variety and various other things like if they are seedless, when fruit is harvested and brix levels. Then I go to youtube, citrus books, citrus forums, FB and then online nurseries. I am very picky about what I acquire so I will spend hours trying to decide which variety to get next. Not only that, citrus trees are not cheap to start with and then you have to add shipping costs.
With figs, I do the same thing as rooted trees are expensive and the same amount of time is invested (3 years) before you decide if it's a keeper. I check out youtube, nurseries, fig forums, and FB. Of course Google gets me started. I look for closed eye, fruit size, flavor, resistance to splitting, and if it will do well in the Southern heat just like you do. I prefer figs that will produce as early as possible.
