I don't think using Shopify and their payments violates the commandment of control. If Shopify payments doens't work out, there are dozens of others of providers.
We run several million through Shopify pay a year, and are very happy with it. Only once have we hit a snag - when we were running preorders last year and our chargebacks were high. Shopify reached out, asked what was going on, understood, and continued as normal.
Shopify pay does NOT like high risk merchants (firearms, supplements, etc.) so if you're in any sort of those spaces you need to go with a different payment provider.
