It's a very bold assumption that a team that cannot manage a monolith will somehow lay a robust groundwork that will be the foundation of a future Netflix-like architecture.
By the way - Netflix started as a monolith, and so did most other big services that are still around.
The rest faded away, crushed by the weight of complexity, trying to be "like Netflix".
There are much better options above copying someone else. Copy is better than letting anything happen, but you should do better. You should learn from Netflix, stackoverflow and the like - no need to remake the same mistakes they did - but your situation is different so copy isn't right either.
