Miniscript inheritence wallets are a good next option, assuming you can sufficiently cooperate with your heirs & other parties involved to secure their xpubs (AND the wallet descripto) beyond your lifetime.
With the descriptor, they'll know your wealth; without it, they can't spend the inheritence, even if the timelock means they have all the necesaary xpubs to do so. You could withold the descriptor, but it needs to be accessible to your heirs in the end. It depends a lot on your particular trust circle & your personal wishes.
But if you trust your heirs & your own capabilities, it's a great dead man's switch setup.
