The ability to use a hardware wallet fully airgapped is only a benefit if the device has a large enough screen to clearly show you the entire contents of every QR code that you scan, and it's only a benefit if you have the discipline to always read it to make sure the text the device shows you (from the QR code) matches what you were expecting (from the transaction you're doing).  Otherwise, there's still potential for a hacker to hack the app you're using for the transaction - or worse, trick you into using a lookalike app.

I'm not badmouthing airgapped hardware wallets though.  I'm a huge fan of a project called Krux, which is fully airgapped, stateless, uses encrypted seed QR codes, and has very active development (they've also won grants from OpenSats.  They're legit).

In my experience, most of the people who jump from hardware wallet to hardware wallet care more about cool gadgets than they care about actual security (I'm not talking about people who test hardware wallets).  I wouldn't even consider a Bitbox.  Look how tiny that screen is.  The smaller the screen, the easier it is for you to make a mistake.

For your needs, I would recommend a Trezor.  Their hardware wallets are fully open source and probably have the most eyes on the code, which means it's safe.  You don't even need the latest model.  Yeah, I know, the new model has a secure element chip, but as Ledger taught us all, keys can be extracted from a secure element chip (P.S. Don't buy a Ledger).  The use of secure element chips is mostly just marketing, because people who don't understand this stuff see that term and think it's what they want, because it uses the word secure.
