It's bitten a couple of friends of mine who use them for remote
monitoring: i.e. boxes you can't get at. Some have killed cards so

Also there's a "fun" new glitch on the RP4: a certain  screen res
disables wifi (!)

They are complex little beasts.

There's a lot of stuff in Raspbian I didn't want so mine ran Lubuntu.
Not used it in a while, though.

Do you mean SDXC? That uses ExFAT. Linux supports that fine:

Anyway, ExFAT is going FOSS:
