Those are your basic options for no-fuss 2%+ cash back cards. If ApplePay is required to earn 2%, then I'd say the majority of those cards are better; my biggest expenses every month are bills (phone, internet, insurance, oil, electricity, etc) and I don't think I can use ApplePay to pay any of those.
