You're asking questions already and looking for input with an open hand, so you're already on the right frame of mind.

Before anything else: just start asking people in your target industry/demographic questions. "Hey, I'm thinking of making a go of this. How do you make money?"

Are you open to creating motion content for any type of situation, so long as it gives you the freedom and compensation you want? Or is your heart set on the contexts you've outlined?

If the former, I'd optimize my efforts on creating a wide surface area from which to learn where the money is for motion visual creators. (Answer: it's probably in advertising)

If the latter, I'd go deep on understanding the business of motion visuals: who pays for them, how much (and how big is the pool?), who decides on them, what the process looks like. Reach out to labels, radio stations, other artists in the same space.
