Does Yubikey 5 NFC or Lighting/USB-C work with bitwarden on iOS

I have decided to get one or two Yubikeys to improve convinience and possibly increase my security. To help me choose which key to get i need to know if these keys are compatible with bitwarden.

Does Yubikey 5 NFC work with iPhone 11 Pro (Lightning/NFC)?
Does Lightning/USB-C work with?
Iphone 6S (Lightning, no NFC)
Ipad Pro 2018 (USB-C, no NFC i think)
