Download bluewallet on your phone.
Build a Seedsigner or buy a foundation passport.
Use the QR scanning feature to pair with bluewallet.
Using QR is easy and ultra secure.
Lots of docs and videos on how to do this and you'll love the process.

This is the most secure I think.
Especially if you build your own SeedSigner.
That way it's all generic parts that aren't BTC related so you don't have to worry about all that supply chain and address risk.
