bitcoinpaperwallet have a page on the security precautions you should be taking when generating a paper wallet here: https://bitcoinpaperwallet.com/#security. It would be worth linking to them somewhere in your guide. The most important ones that you have missed from your guide are to running the wallet generator on a permanently airgapped machine, or at the very least, with your internet connection turned off (although I would not recommend this), and using a dumb printer to print the wallet, since smart printers both store copies of what they have printed on internal memory and are more prone to being hacked.

I wouldn't gift someone a pre-initialized hardware wallet with bitcoin already loaded on to it. Even if that other person fully trusts that I'm not still holding a copy of their seed, it's teaching them bad security practices. Better to gift them a hardware wallet, let them set it up themselves, and then send them some BTC.
