cpanel can only do so much. You still have to set up a database. Sure, you could probably do it all with cpanel, but there’s still maintenance. I think what they need is NOT self hosted. Something serverless.
Ultimately, I think the solution needs to be a new Wordpress competitor that takes advantage of cloud technologies and can be moved around easily if you need to switch hosts. Something that has lots of integration options so you can just choose your own cdn, database host, app host, etc.
But even then, once you want to go outside the box and make something that doesn’t have a template, you’re gonna touch code, or a terminal.
