One of the reasons I know Bitcoin is the future is the clear difference in online interactions in this community turning out positive when anywhere else they would devolve into insults or just end abruptly =) Let's see if my thinking would help you.
First: here is a presentation I was watching about multi-sig. I think it would make your goal possible but it does have the higher complexity. (or cost- everyone gets their own hardware wallet)

However, like you said, maybe attempting multi-sig for extra security is not the explicit goal here.
How about a single hardware wallet > watch-only wallets (same public key) on each of your family's devices? https://bluewallet.io/watch-only/
-Hardware Wallet located in your possession / family safe / family trust.
-BlueWallet app so your family can easily create their own other wallets + generate receiving addresses for the FamilyVault wallet and contribute to it.
This at least achieves the awareness/tracking and contribution for the Vault wallet by each user, but the multi-person approval feature would be offloaded to a physical process of taking possession of the master hardware device.
Yeah it is hard to consider the person on the other end when we all strive to be so invisible.
I will look into this. I was thinking of some sort of way to have the hardware master vault on multi-sig, but each watch only wallet under the same master seed phrase + whatever private password phrase they choose and no multi sig.
If that could happen then I think most of what I want can happen. They could use the hardware wallet to access their vault under their passphrase to spend funds. The main family vault on the hardware wallet could not be spent by the individual but the balance should be viewable and xpubs exportable so all family members can still verify funds in the main vault are good.
The only missing piece of this would be the fact that all funds are separate and members would need to contribute to the main vault rather than the sum of everyone's balance be apart of it.
I definitely have a vision in my head on how to solve that last piece but there is no way I could do it on my own. It will require building a wallet from the ground up.
Ordered some hardware wallets to see if I can at least execute on everything else though.
