I’d say a Keychron board with either Gazzew U4 or Zeal Zilent V2 switches. Their plastic frame keyboards are a great value and high quality. The Gazzew U4s are an absolutely amazingly quiet switch with a perfect bump at the very beginning of the press.
I recently got a Dell Latitude 14 2-in-1 with the AMD 8840U, Put on the latest Fedora Kinoite and the fingerprint reader works FYI.
