CashApp made most of their money through Bitcoin and the exchange fees (something like 70% in 2021?).
Additionally, they charge extra for instant transfers in and out of CashApp. I believe its 1.5%.
Lastly, they also make money by keeping the Cash in the CashApp/Square network. Since it is all within Block, they will not have to pay interchange fees when a customer pays with CashApp to a Square merchant.
