Standardization has been the trick for us.
A) All food storage containers use the same lids, but there are three different depths (0.9L, 1.2L, 1.6 L). These are used for everything from lunch boxes for both adults and children, storing leftovers, to christmas cookies. They are stackable, and fit perfectly in one kitchen drawer. And of course they can go directly from the freezer to the microwave, and are dishwaster proof.
B) There are two types of storage solutions in our house; IKEA kallax/expedit as open shelves or with different types of boxes, or wire baskets. If the need changes in one room, we can take shelves, baskets or boxes from a different room. The dirty clothes are kept in wire baskets; one for each category. Everyone is responsible for sorting as they drop their clothes to be washed. One wire basket equals one load, so when it is full it gets dumped into the machine by whoever is in the bathroom. No extra brainpower required, just set the machine to what it says on the basket. Now we usually sort, but when we had two full jobs and two handicapped toddlers, we usually just dumped the clean clothes in a new wire basket, and put into a free shelf. No sorting of folding required, if you need clean clothes you can find them in a wire basket in the closet.
C) No double of triple sets of dinner plates and cutlery; the everyday stuff is good enough for Christmas. The plates are undecorated but a variety of solid colors; some Höganäs, and some Ikea Dinera. These can always be supplemented by similar stuff, even if they stop selling them, and it looks like we intended them to be different instead of running out of the right ones. The cutlery is relatively high quality, because unsharp knives are annoying.
D) The kids still have paper books, I have gone 90 % digital. All the paperbacks are now in my kindle. (I used to have several hundreds stacked on top of each other in shelves all around the house).
