Next step in learning Wix Studio Essentials

Hi everyone, I’m a graphic designer who is just getting started with Wix Studio.
I’ve started with the “Wix Studio Essentials” video course, but I’m now looking for the next video course. What would you recommend?
I feel a bit lost among all the videos and resources in Wix Studio Academy. I’m also especially interested in learning how to hand the site over to the client in an organized way.

It’s not very detailed, but Wix answers a similar question here: https://www.wix.com/studio/academy/tutorials/how-to-handover-your-site-to-clients
