My humble opinion about this. If you use Ledger Hardware + Ledger Live App + Connect Ledger Bitcoin Node. You create yourself a possible point of failure which is something I don’t like. Even if Ledger people are really well intentioned this kind of setup might have some vulnerabilities. So at least you can use Sparrow in Desktop as a wallet and use your ledger as a signature device. Or even better create a multisig using blue wallet from your phone and use it as a signing device + ledger. So you will have a device for signing completely isolated from computer at least. Or you don’t I don’t know I might act paranoid when it comes to have a secure setup. But my last advice never transfer your funda before you test and feel really comfortable with your setup.
