Then just lay a piece of black plastic over it and weigh it down with a couple of stones or scoops of soil. It'll be gone in 6 months. Bocking 4 or 14 will not "travel" --- it will get slightly larger with each passing year, but it's not suddenly going to pop up 10 feet away.
I would imagine that eventually, anything will die that is planted at the base of a pecan tree that will grow to 50 feet tall. That includes comfrey.

Shipping is another problem. Probably 3 fits per 18 wheeler. That's gonna factor into the price..
It will sink if it sits on the ground, which may be why they want flex joints. I think I had that happen to me with hard elbows out the bottom.

maybe this will help you get started http://iswm.nctcog.org/training/Ponds_Class_082913/Ponds_handouts_combined.pdf

So you would have to calculate average inputs/ outputs month by month and see what the largest cumulative total would be, and then add some extra to account for unforeseen events.

Yes there is a lot of stuff to learn in permaculture, I am in no way done learning myself.

A cistern has the benefits of less evaporation issues, as well as less plant mater sucking up water from the store of water. Your not in a desert though so this might not be a huge issue.
Both cisterns and ponds tend to become breeding grounds for insects and possibly viruses. However a cistern tends to be the easier to manage these issues. While a pond it is more about mitigating than complete management.
A cistern can be an eye sore if just left above ground but if you opt for a buried one they can blend in. A pond however is typically an attractive element and a pond can add to the beauty of your place.
Both ponds and cisterns do need some upkeep. A cistern will need to be drained and cleaned occasionally as sediment builds up in the bottom. A pond will need a bit of plant life management as well as possible dredging of accumulated organic matter and sediment. Ponds however are hard to know what to expect, as they are dependent upon how you build it what goes into it and so many other factors. A pond could go for years with no maintenance, or it could take intense maintenance 2 times a year, or even every few months. It really depends a lot on the pond construction, the region, the wildlife, etc... A cistern would be the more predictable one. As well as the more instant option. As a pond will require more start up maintenance to get it going, while a cistern will pretty much be ready to go once built or installed.
Over all you might notice cisterns seem to win out for your application. I personally prefer a pond, which is why I bought land with a pond. However for what your talking about needing this water reserve for I would say opting for cisterns would likely be the best bang for your buck.
Now the big question might be build your own, or buy one? You can make simple concrete box cisterns pretty easy, both underground or above. Buying an cistern gives you the quick fix of getting it right away, and usually with the plumbing options ready to go.
