The historic solution is in a safety deposit box at a bank. If you're talking about things like crypto cold wallets which might be extremely valuable, why risk leaving it at home? The cost for small items like documents tends to be reasonable. Good practice for things like ownership deeds and wills.

I don't think the average home thief would know what to do with a printout of your 2FA recovery code especially if it's buried in other paperwork. The real risk is loss from negligence or natural disaster.
