NOTE: I work at a FAANG co now and I can tell you that the learning experience can be hit or miss in FAANG (so, 3. is not as bad as it sounds).
I am not trying to decide my next job, but I see a lot of co-workers obsess about RSUs in FAANG (when they can be brought in open market).
If you're unsure or feel uncomfortable with the risk, then the all-cash option (#2) would be better.
As for option #3, it would really depend on the specific company - difficult to evaluate without knowing. It's hard to know if taking a bet on a non-FAANG company's stock is a good idea without an understanding of what space they're in, what stage they're at, etc.
I'm assuming #2 is Netflix.
