Securing BIP39 Phrases and Password Manager Master Password

I am looking for a review of the solution to store my Ledger Nano S BIP39 recovery phrase as well as my password manager usage.
This solution is mostly based on this video.

Few points that I think require explanation

  1. Emergency access process for Bitwarden explained here. Essentially if I get hit by a bus, my partner will be able to request recovery and if I dont reject approval via email she will get full access to Bitwarden.
  2. Devices I am planning to purchase : 2 x Yubico – YubiKey 5C NFC; 1 x Apricorn ASK3-NXC-4GB
  3. Create backup Yubikey with identical PGP keys
  4. Restore of Bitwarden from Google Drive + Dropbox tested succesfully.

Questions

  1. Are there any major flaws that you see with this approach?
  2. Any further improvements that can be added in terms of security and/or usability?
  3. Any recovery process flaws?

Many thanks in advance.
