The Samourai wallets contents were fully recovered and moved to an external wallet via the Sparrow 1.9 wallet.
This is that worked for me and I'm posting it here since it is different from the resources I found online, hoping it is useful and helpful to other ex-Samourai users.
The process on Sparrow 1.9 was as follows:
  • Import wallet
    • Mnemonic words (BIP39) (*)
    • Use 12 words
    • Use passphrase? YES
  • Discover wallet
    • (it shows: Balance 0; sats 0)
  • Settings (of the imported wallet)
    • Policy Type: Single Signature
    • Script Type (change it to:)
      • Nested Segwit (P2SH-P2WPKH)
    • Change Keystores? YES
    • New or Imported Software wallet
      • Repeat (*)
    • Create Keystore
    • Import Default Account #0
    • Re-enter the BIP39 passphrase
  • Apply
  • Change wallet address? YES
Hopefully after all that the Balance should update to the correct value and you will be able to move your funds elsewhere.
Thanks to all for your words of wisdom and support. Next up I will devote myself to setup my own Bitcoin and Lightning nodes and zap like a mad man.
