Netflix & Google work-life balance is actually pretty good. Amazon it's very variable - some teams have decent hours, others work you to the bone. Apple has a reputation for preventing engineers from having a life, though it might've gotten better since Steve Jobs died. Facebook is probably similar to Apple overall - you work harder than at Google, and also have less time for reflection (Facebook is all about metrics and hitting the numbers).
I would shop around and see if you can get an offer from a FAANG or Bay Area growth company before moving out, though. They'll often pay your relocation, and it's a lot less stressful than moving out, paying Bay Area rents, and hoping you get a job without any firm commitments.
Also beware of down-leveling. People who have not previously worked at a FAANG or hot growth company often take a title demotion (but salary bump) when moving to one of them. I've heard of folks - in the Bay Area, but at a bank rather than a tech company - going from being a Director with ~20 people under them to an IC at Facebook (but making more money), and of people being VPs at their previous company but going back to being an IC to work at Stripe. If you were a senior-level engineer making $150K at SLC you might get a mid-level engineer position at a FANG for maybe $250K, which is basically a wash after CoL adjustments (actually probably a step back in quality of life, because Bay Area housing & traffic is so terrible). But then you have a FANG on your resume, and you can either stick with it and get promoted into those $500K-$1M roles once you get back into management & senior engineering, or you can turn it into a very senior engineering or leadership position at an up & coming startup.
