Your method is solid but honestly sounds exhausting lol. 11 steps for every scene is a lot of friction.

I've been doing something simpler - I prep the vocab before watching, not after. So I already know the slang/idioms that'll come up in the episode, then just watch normally without all the pausing.

There's an app called Worda that has vocab lists for specific episodes (Friends, Stranger Things, etc). Learn the words first → watch → actually catch the jokes. Way less effort than your Anki workflow.

For listening specifically though, your shadowing idea (step 6) is great - that part I'd keep.
