Does this thing actually hold anything like collectibles or does it just take up a lot of space? and how about the vault door thing that matches?
The vault door can be used to make secure rooms for collectibles/art etc. The vault itself only holds cash (and sims, if you trap them inside). Storing cash in vaults effectively increases maximum wealth beyond the max limit set by the game. A sim "claims" a vault by adding cash to it. An empty vault is free to be claimed by any sim that has some simoleons.
If you make a bank on a community lot (Generic, Library or maybe Retail if you want to own a bank and have customers), then it's a fun place to send Clubs of Kleptos, Criminals and rich sims. You could also make it an active workplace/office for sims in computer/writing based careers like Freelance Writing/Programming, Social Media, Law, Education etc.
The vault/vault door can also be used for trapping/holding sims (possibly pets too) for your more deviant sims. Like any locked door sims would eventually die of starvation if they have no access to food, but can escape if you leave the lot. Not sure if they can escape the vault object.
