> usually those rates are extremely subject to change, require quarterly activation
That's not true. I'm not aware of any US credit card offering 2% cash back on all purchases that regularly changes this 2% rate or requires quarterly activation for the 2% rate. If you can name even one 2% cash back card that does this, please do.
> variable APR
The Apple Card also has a variable APR. The Apple Card Customer Agreement says that the APR is "15.49% to 26.49% when you open your account" and "After that, this APR will vary with the market based on the Prime Rate."[2]

> high foreign transaction fees
The Bread Cashback Card (American Express) and SoFi Credit Card (MasterCard) manage to offer 2% cash back on all purchases with no foreign transaction fee or annual fee.
