Is Square an option for payment in any of the e-commerce related plugins?

I'm doing some stuff with a Yoga studio now. They will have classes, workshops, and services.
Classes are (semi) regular group sessions - Beginning Yoga for example

Workshops are one off, typically multi-day events or seminars - How to get the most out of Ayurveda, for exmaple

Services are appointments - Acupressure, for example.

They are using Square as their POS and want to have everything clear through that. Square offers some of that functionality but not in a way that works for us for online booking.

Is Square a payment option in Marketpress, Appointments+, or Events+?
