Everybody's living situation is individual. You have to assess your potential loss risks yourself.

Cold, offline and analog storage of mnemonic recovery words, if you use an optional additional mnemonic passphrase and the passphrase for the storage media encryption is preferable. Mnemonic recovery words and optional additional mnemonic passphrase for the wallet need to be stored separately, never together. I would store the passphrase for the storage encryption also separately from both.

I'd use quality archival paper and archival document safe ink. For protection against loss by fire, I stamped all required secrets on stainless steel washers. Hiding the metal stuff is a bit more difficult, but messy corners or boxes with seemingly worthless stuff are a good start. Be creative...

Paper isn't difficult to hide (a thief usually doesn't spend a lot of time searching for some paper stuff). Burglars look for money (leave some bait money which is easy to find to satisfy them), precious items, stuff that can be quickly turned into money.

You should of course keep a low profile and don't brag with your crypto coins or that you're heavy into crypto. If you don't keep a low profile, you're plain stupid and shout out for trouble.
