Hardware Cold Wallet Q’s

Okay so been using my Gemini pro AI to learn about and research cold wallets.

From my research it sounds like I want a hardware (specifically COLD) wallet that has these features:
• Air gapped,
• Open source,
• EAL6+ graded secure elements,
• On device display,
• Bitcoin only,
• Allows for dice roll entropy for seed phrase generation.

Missing any requirements?
I think I’m okay without Multi-Sig, I don’t have that many Sats where I feel I need that level of security.

- I’ll also create a Pass Phrase.

From all of this it sounds like the, Keystone 3Pro hardware wallet with its firmware flashed to Bitcoin only is my best option.
Any other contenders that’s fit the above criteria you suggest or use?

Thanks guys! Just wanted to ask yall before I spend my Fiat.
