Not that I acknowledge storing anything, home, cabin or cached in between.
whatever you store, remember to store spices, etc.
There is a process called appetite fatigue that makes people not want to eat the same bland foods
Store LOTS of salt (25 pound bags), then add pepper, chipotle, chili powder, granulated garlic, dehydrated onions, cinnamon, nutmeg, dried parsley/basil, chicken/beef bouillon, tomato powder, lemon juice/lime juice concentrates, honey, preserves (strawberry/raspberry, molasses etc.
Then add vitamins, the ones that are like gummy bears do double duty as a sweet too.
Get some comfort foods. Only you know what they are. Me, I like my bacon, butter and cheese. If I were storing, I would have all of them canned
The spices, etc will make wheat berries, rice and beans a LOT easier to take.
As far as the wally world 30 day supplies, etc, watch the (lack of) protein in them and adjust accordingly. I personally found the sodium level of some of the items over the top, but if you make a batch of plain rice and then mix in that stuff, the seasoning level is more in line
Buy a foodsaver and you can drypack things you like in a mason jar that has been vacuumed into a long term storage method into a manageable size.
I've purchased salted cod and then vac packed it and eaten it over a year later. Between the salt, being sealed and the anoxic environment, it wasn't even possible to tell it was 'old' cod.
In terms of rice, get a type you like. Brown rice has better nutrition and most 'american' rice is pretty awful from a nutrition standpoint. I prefer basmati rice for a nuttier flavor, or jasmine for a more fragrant sweeter flavor. (see mentioned appetite fatigue)
There's a LDS cannery in Worcester, you can bring a truck and have a pretty good jump on storage in 1 trip, with stuff canned and stored that is immediately ready for long term storage.
Last tip....buy LOTS of can openers; it would suck to have all those cans and no way to open them
