I deal with ecom a lot at work, in which we build out ecomm systems for large(er) companies.
Just about everything is going to AEM with elastic path/ some other ecomm apis and headless frontends (mostly React, namely NextJS, some unfortunately on Gatsby).
I'm not sure what is happening with all the old Magento platforms since Adobe took it over, but I don't think we do much work in Magento any more.
