Need recommendations for a portable low profile keeb

My partner loves her GMK67 with outemu panda switches I built for her a while ago. Now that she has to go in the office she constantly complains how shitty the keyboards are.

What would you recommend for a low profile portable keyboard to give a similar experience the GMK67/Panda that is safe to throw in a backpack, but also a bit quieter for an office setting?

I was looking at the Nuphy Air60 since it has a case option, but I don't know what switch would be good, maybe Wisteria or Moss?

Also looked at the Keychron, but from the switch descriptions only the Mint and Banana sounded close to a switch I would want, but nothing is currently in stock in a 60% layout.

Am I looking in the right direction, or are there other recommendations?
