Cris Bessette

I had one (maybe more?)  of these show up repeatedly at my property in North Georgia last year.  Started eating the goldfish out of an ornamental pond in front of my house.
Being partial to my fish, I decided this leggy bird wasn't beneficial to their survival.  

I took a ladder and some other items and laid them across the pond to at least give some places for the fish to hide, if not scare big bird away.
It seemed to work, I still have plenty of fish left.

I stuck a peach pit randomly in the ground about 4-5 years ago, this year I ate the 10 or so peaches the resulting tree produced.
This tree actually had better peaches than the 3 or 4 other peach trees I bought and planted.

Other trees I've grown from seed:  Bald cypress, coffee, tea (bush actually), various varieties of citrus, American persimmon, paw paw, windmill palm.

I live in North Georgia, I suggest you plant as many types of fruit and varieties of them as possible, then no matter what happens, you will always get fruit of some kind.

I try any type of fruit, any variety that I think might work here.  I even have a few varieties of citrus that fruit for me.

A type of nitrogen fixing corn that is native to Mexico that might be big thing in the coming years.

This is something I just came across this morning, not exactly what you were looking for, but it's pretty interesting anyways.

It's a nitrogen fixing corn from Mexico:

Siberian Pea Shrub is the first thing that comes to mind for me. It seems to meet most of your requirements though I don't know how it does in drought situations.

About 5 years ago I planted two kiwi vines.  I bought and planted one labeled FEMALE and one labeled MALE.  
As luck would have it, they finally both bloomed this year, and both are  clearly FEMALE.

How do nurseries even know if a vine/tree is one gender or the other before they have obvious sex characteristics like flowers?

I've bought a third kiwi vine, supposedly male, but I hate to plant it just to find out in 4-5 years that it is also female.

Good luck with the kumquat.  My personal opinion is that kumquat is one of the best choices for cold hardy citrus.
Mine took a beating last winter, might have to dig them back up and repot, grow indoors for another year or two
so that they will have more adult resistance to cold.

Make sure you have things that eat mosquito larvae.  Frogs and fish think they are yummy.  Dragon flies. Birds.  A healthy eco-system in your pond will attract mosquito predators.

Often people pull the whole "rip up the whole patch and replant" when they keep the strawberries in a contained, linear row under plastic that prevents runners from creating new plants. If you let strawberries do their thing, they'll keep going indefinitely.

That's pretty much what I was guessing.  Putting strawberry plants in an artificial situation results in the necessity for replacement.  
Letting them grow like they do in nature, should result in self-replacing plants.
