you should also look up bip38 paper wallets
the reason i recommending it is, secure redundancy will never be so affordable any other way. also while bitcoin addresses are somewhat quantum resistant in a quantum supremacy setting a deterministically generated hierarchic private key (anything seed based really) can be generated from any other private key from the same hierarchy and once you transact a single time your pubkey is exposed... basically you are fucking screwed if quantum computers become a thing and you trust these gadgets. but you can also get screwed a dozen other ways with them.
secure redundancy means you store your secret securely (from theft or confiscation) and at multiple locations so a single disaster won't destroy them all.
for inheritance and stuff also look up shamirs for secret sharing!
