I really like your design!
In my XP NFT is the most reliable and simple and is easy to set up and reuse (this is my recommendation).The fully submerged bubble pots and aqua phonics are what you need if you want best yield and quickest results,although if a failure occurs they will be effected the most compared to other systems.
Flood and drain (ebb and flow) systems are again great,also they won't fade away dramatically if an outage occurs,but they are a pain in the sense that you need to replenish the substrate,you don't have to always do this,but I have found it difficult to remove all the previous old roots and this brings in detrimental pests and bugs.
Soil and ORGANICS are the way to go IMO! All these chemicals are killing us slowly.
I have thought about combining the two ie ORGANICS and hydro although you will need to dial in the nutrients precisely as with the quick growth, deficiencies would most likely set in fast.
As another poster pointed out.If we are looking at survival,then hydro is a no no,unless you have solar power,but even still you maybe putting all eggs in one basket (solar systems could be destroyed by EMP)..I feel that is not wise.As the same poster mentioned,a gravity system is what would be ideal under those set of circumstances.
An idea that has occurred to my imagination,was if you could divert a river flow (or utilize it) and have a flow of water over rocks,which as you build it up,would contain different grades of material,say large rocks,smaller rocks,gravel and then possibly soil or rock wool?
Thanks for. Sharing your ideas,you have sparked my passion for growing veg,now the spring is on the way! happy season!

Good Post OP!
I'd suggest, if you haven't already, read more about what creates the best root growth. From my reading you get way more root surface when they are suspended in air and not in a medium, cube you mentioned. Also the nutrient spray size droplet matters when suspended in air. As fine a mist as possible, like a fog, stimulates intense root surface growth.
I built a small system but never got the best mist sprayers so always felt I wasn't doing 'the best'.
It's an amazing subject to be honest. Of course you didn't go into lighting which is a major key to the whole growing of any plants. I guess that's a detailed thread all by itself!!!

If you used this system near a pond do you think you could use the pond water as a nutrient ready water source similar to an aquaponic system?
I ask as I have toyed with the idea myself, setting up an aquaponic system utilising a natural source as opposed to a made version.
