Regarding paddle.com - I should have mentioned that their payout schedule can be a drawback.
They pay all sales for the current month on the 15th of the next month.
So, if you make a sale on 1 July , you will wait until 15 August for your payment to be sent - 6 weeks.
If you make a sale on 31 July, you will also wait until 15 August for your payment to be sent - but it's only 2 weeks.
But either way, it's longer that PayPal or Stripe, and some other processors.
When you have established a good account with them, low chargebacks/refunds, etc - you can apply to receive bi-monthly payments, but they're less inclined to do this with high ticket items.
