Is it better to only use your credit cards for payments, and only using your debit to pay for the credit card payment

Credit cards hold various advantages like the rewards (cashback/miles/points), they help to track your credit rating so you can get loans and they are easier to cancel payments when compared to other forms of payment.

Of course this will depend on your use case and how disciplined you are at paying back on time and not over spending.
