I’ve asked this a couple times and I haven’t gotten a clear answer, for 100% (and 95%) do you have to watch/unlock every cutscene? By this I mean do you have to beat 1000, 1250, 1500, etc. Thanks for reading!

Nope. You're fine w/o getting cutscenes.

I did answer that, Pokecubes. https://gyazo.com/1b202d95fa6acc0993fa0d2b2a6085ac
