A hardware wallet is the best on your list because it's Airgapped, good to store large funds and for long-term hodli. If you have an old PC, you can also try electrum cold storage wallet. You generate your keys on an airgapped device. i.e you don't connect the PC to the internet and create a watch only wallet to sign, broadcast and track your transaction.
