I investigated a bit about this and found Square promising because it allows creating a link to allow customers engage in a subscription, which is super helpful to not code such a flow when validating a product. I don't know whether Paddle supports this but a customer is super happy with them, it was also super simple to integrate from the developer side. Thanks for the list.
