I donโt know what you and your friend consider a significant amount, but you might want to have him look into getting a Trezor.
For shorter term (non-cold) storage, Iโd personally stay away from any wallets that arenโt bitcoin-only. BlueWallet is a good choice.
Thanks for the thoughtful suggestions!๐๐๐
Bitbox (bitcoin only) or coldcard
