That' pretty much it. However you can of course fund any public address any time once it's been created so you could have addresses like savings, the kids colleague fund, spending etc etc.
Most of them you wouldn't use in your day-to-day life so they don't need to be present in any wallet or device you have which is exposed to the internet.
The you can have one address for frequent use which you have on your pc (in an encrypted wallet like electrum, secured by a passphrase) and on your phone. If that address were to ever get compromised your exposure to loss is minimal.
I do have two cold storage metal card (identical) which I've had for years and those I don't even have on my pen-drives. It's a BIP38 encrypted key and the cards are heat resistant to 1,400 degrees Celsius. Those are the safest key storage devices one can have. Imo anyway
