Separate Fridge Please? And other storage issues.

I need to be able to keep a fridge in my sims' kitchen where only household members have access, to store things like bread and cheese that are ingredients but sims will also just eat them as-is, and also things like the pie I just cooked for the fair.
I also need a fridge that I can put in the publicly accessible space of my house so that club members and other guests have access to whatever food I put in it for their comfort as a good host.

I need these two fridges to have separate inventories!

Even better, since the contents of the fridge are always a randomised jumble with no way of sorting them and I can only see a maximum of ten items at a time because the inventory window is tiny and can't be expanded, if I could have several fridges with separate inventories, I would be able to put all the garden produce in one fridge, all the bread, cheese, conserves, milk, etc in another fridge, and then the cooked meals ready for anyone to eat when they're hungry out in the public fridge. If these happened to be half-sized fridges that I could stack, that would make them look like a conventional double-door fridge-freezer unit, too.

The picnic basket doesn't refrigerate. The camping coolers aren't storage devices - you can get a drink or a quick meal out of them, but you can't put food in them. All of the actual fridges store to a common inventory so the food you put in one is accessible from all. I don't want to try a market stall because I'm not selling the food, it's just there if my guests are hungry.

I know that every keepsake box has its own inventory separate from all others, so it is possible to do this. I need a way to apply this technology to fridges.

While I'm thinking about it, it would be great if we could also apply this technology to bookshelves. I could have my collection of magic tomes in the family-only sitting room and leave a regular bookshelf out in the living room with books that I don't really mind if my guests steal them. Sim guests stealing stuff is a constant problem - whether it's produce from the garden, books from the bookshelf, or hand-crafted violins that I will sometimes find left lying around in other worlds when I visit there. They just forget it's not theirs and put it in their personal inventory instead of putting it back where they found it. And magic tomes aren't easy to replace!

Theft prevention goes for toy boxes too. I don't mind so much if the kids from the club steal a 20 simoleon toy, but some of the toys are actually pretty expensive and these always seem to be the ones that go missing when the club comes over to hang out. If we could combine the functionality of each toybox being its own separate storage and also the functionality of kids putting the toys back in the toybox they got them from, I'd be able to protect the expensive toys from casual larceny.

I had to quit using "off grid" in my game because my kids were constantly getting food poisoning from eating produce (irl I've been off grid for over 15 years and never had any health problems from it) and I had to quit using the "reduce and recycle" because there doesn't seem to be any way to prevent insect swarms taking over. That leaves "simple living" as the only realistic lot challenge available to play with, and it's incredibly annoying to go to cook some grilled cheese and discover your guests just ate the last of the cheese. Or, for that matter, to realise that your impeccable pie for the village fair is missing a slice.
