Which Smart Card to choose for Librem 5?

Is there a list somewhere what is working out of the box on the phone and what does not?
@amosbatto: In one of our last conversations it came out, that contacts app also still needs some work.

And with out of the box I mean: Todd can give the phone to his daughters and they can start using it without the usual hints like: “Oh there is a flatpak bla, bla, bla thing you can pack, just check this repo here …” But out of the box for non-developer end users which was the original promise. Otherwise I can order a pinephone …
