Thank you @jacob-murphy for raising this important topic! I’m exactly in the same situation as a video & live streaming agency.
Strange fact: I had access and used the exact same Wix Video layouts as in the classic Wix editor on 4 of my Editor X websites since March until… this month. Since I don’t understand what happened suddenly, I raised a ticket and I was told exactly the same thing as you: I shouldn’t have access to other layouts than the (terrible) slider one and that’s it.
At least for the moment but I hope improvements / updates will come very soon as clients’ projects continue and it’s really extremely embarassing 
Wix video teams, please help!
Ok we can always find some turnaround but for me, video is a core business and video apps integrations are one of the main reasons I’m using Wix and Editor X to rationalize on all platforms.
Any news, any update on this is more than welcome anyone.
Thanks in advance
