Depends on what exactly you mean by "Cash Card".
The Apple Cash feature in the Wallet app on an iPhone has never had a physical card to go with it. Its strictly a digital debit account you can use with Apple Pay in physical stores, websites and in apps.

If you mean a gift card with the Apple logo on it, then yes, Apple still makes those, those are gift cards with a certain amount of money you can add to them, and can be used in Apple Stores to buy hardware and accessories.
