There are hardware wallets as well. I use Trezor, can't tell you if it's the best, it's just what I use. The main thing is to have a physical record of your wallet's BIP39 seed phrase (the words), rather than relying on electronic storage. The list of words should be in a form which is essentially indestructible.
One approach is stamping or etching the words or their numeric codes from the BIP39 list into a titanium coupon. That should probably survive just about anything except the Earth falling into the sun. The titanium blanks are available online.
