Ah Mary-Anne! Separate from CompanyCam, my No. 1 day-to-day priority, I've thought about doing the same with some of my other side businesses that I do for fun (Session Solos, JTal Guitars, etc.). The content creation stuff has been the most rewarding and takes up more time than the others, so I've thought about rolling it all up under that. I've got some experience with it in terms of being in S-Corps, multiple LLC setups in the past but not enough to guide anyone but myself yet.
This is me saying, I'm considering the same, on a much smaller level than you (way smaller lol) and I'm willing to trade notes while not having a ton of answers yet.
