Nice tips. There are however also other things that you might consider growing, especially, when you have smaller garden or more stylish oriented, fruits like maracuja are a perfect landscaping choice as their flowers can be seen throughout the year and they are really beautiful.
Also you could try Ananas comosus, but cover it well for the frosts (which is deadly for most varieties), but you can grow this lovely plant also in small pots (really small, not like nanas). There was one time that I had about 20 plants, all from the store bought fruit and of these, 10 I gave away, 6 fruited and 4 died in sudden late frosts about 2 years ago. Now I have only few pieces (5 to 10), just to have some fruit throughout the year. Pineapples are very expensive here (3€ a rotten piece), so it was a good time investmen on my part.
They however take very long to ripen and require specific conditions, otherwise the fruit will be too acidic (like citrons or lemons, sour) or undeveloped. I had in my life about 10 homegrown pineapples from my region and I must say, that it's way better fresh from the plant than from the store (sometimes they were even ripening 15 months, sometimes I had to force them to ripen, but they always ended up well colored and tasty).
Also, if you choose landscaping plants with a purpose (such as nanas), you can always view alphabetical list of Floridata, real cool, only the best of the best got in, there's also a wide list of palm trees along with reported frost damage...
