WebAuthn for relying parties (what the bank is in this scenario) just isn't very hard. And you don't end up with any long term secrets at all, so that makes the security story easier. But I sadly do not expect banks to adopt it anyway.
I don't see what a Yubikey with NFC is getting you here. For a laptop/desktop user any of the Security Key products in an appropriate USB form factor (USB C for some newer laptops otherwise USB A) would be suitable.
The high end phones are or in the case of the iPhone very shortly will be WebAuthn platform authenticators, there's nothing extra to buy. Apple released a video of the pleasant UX journey they want to promote, obviously being Apple it doesn't actually say this would work on non-Apple devices but I use it already so I know it does.
