I’ve found though that often when clients say they need something that only a headless solution can provide, they actually don’t truly need it. And once the actual requirements are focused, a well built Shopify theme is plenty sufficient.
Maybe we are working at a different scale of companies though.
The main advantage of headless to me is the ability to get the speed of the site way up. But the nature of e-commerce is to add tons of pixels and other junk so it can defeat the advantages (and much harder to talk them out of adding pixels sadly…)
