Don't get a blockchain lockbox.
That's basically a cheap version of the nano s with support for way less coins than the original nano s and AFAIK also only working with the blockchain.com interface. And it costs almost the same.
Better just get the original ledger nano s. Costs the same, but you can store way more than just 4 different coins on it. And you can use any compatible wallet you want (ledger live, electrum, wasabi, etc..).
Yubikey, as already mentioned, is not a hardware wallet, but a security-token. It is being used for 2FA (to secure accounts which support 2 FA) and can be used for other stuff too (e.g. decrypting your harddrive and unlocking your computer / locking it upon removing). But it can't hold your seed or private keys.
For secure crypto storage -> Hardware wallet For securing accounts with 2 FA -> Security-token (e.g. yubikey)
