Strategies for getting crypto off exchanges

There seems to be multiple ways to get crypto off exchanges I was wondering if anyone here found the most practical and least costly way with cold storage?

I have put some thought into this and think the best way to secure your crypto is to get a hard wallet like a ledger and store the ledger in a safety deposit box.

I have to put more research into who gives the best deals on safety deposit boxes put seems like most US banks still have the option for an annual cost around $80-150, depending on the size.

Total cost would be transfer fees + $150 for ledger nano X + $80-150/yr for safety deposit box + $ not gained from staking.

I’m accustomed to using hot wallets to make staking easier but would appreciate any pointers anyone has about cold storage.
