I'm working on getting food to grow that comes back every year,
Excellent!
I am doing the same, but in a very different zone.
So long, what I've learned is not to buy plants from any nursery. If they have to reseed, better to check if these seeds are able to grow on their own: good seeds are easier to find and deliver than good plants. You are not guaranteed that the very first seeds will not produce unfertile hybrids, but at least you will know that, in case they are fertile, they are able to grow again without special care.
However, gardens evolve, so be prepared that the beds where carrots thrive one year, will be better for other type of crops the next years (or seasons). What I want to do now with the seeds is to keep a few in bags as insurance, and let the rest reseed at leisure. If there is ever too many plants of the same type, I will give them the weed treatment: chop & drop the excedent.
I mix this with perennial plants: fruit trees and edible bushes, which usually are less productive but are easy to work with.
