The floor is 1.5%. I don’t know of any 2% card without any catch (the Apple Card’s being that you have to use Apple Pay, which is still not available at many online merchants).
Personally, I use a 2.625% cash back card with the "catch" being that I have to have enough stock in their subsidiary brokerage to qualify for the top rewards tier. Since I just buy and hold SP500 ETFs, this is an easy requirement.
