Unique systems are a really bad idea. Craig Raw has some advice on best practice for cold storage on his website which I think would be good for most people to look at:
https://sparrowwallet.com/docs/best-practices.html
For true cold storage on Sparrow, you need to:
Connect to a private Electrum server
Use a good, unique password on your wallet
Employ at least a 2-of-3 multisig setup
Require hardware wallets from different vendors for a quorum
Secure the hardware wallets (and backups) in different locations
Minimize the time your cold storage wallet is open in Sparrow (mixing to cold storage is one good reason to keep it open however)
