I had a rule after my time working a peer equivalent to FAANG: if I consistently find myself the obviously smartest person in the room, I should go else where. There has been so much joy working in an environment where there are people who are more experienced, skilled, and/or talented than me.
At my current startup, which has been just amazingly successful, our engineering team hires a lot of people who are a lot like how you sound: no dummy and also emotionally intelligent/mature. It's been such a wonderful experience. I never have to hear any silly debates over the nuances of some irrelevant issues so some people can proof their intelligence. People know what the company's business is and just worry about that. Most of the times we work a 9 to 5 (10 to 6 because of Bay Area traffic) and go home. It's taught me a lot about startups and what it takes to succeed. Having the smartest people around working for you is one possible path but there are other very viable alternatives. I've also worked at companies with lots of former FAANG engineers, several Ph.D., and 3 full CS professors that burned that down ignominiously.
I was fortunate enough to work in an environment, where I was the "below-average IQ person," and I am not below-average, but I worked with some fairly smart cookies.
I know that some of my co-workers looked at me with disdain; but I was honored that most did not.
Working with frustrating people has been a very useful part of my career. As a manager, I had to make life-changing decisions for employees, and it was important for me to be empirical in my decision-making.
It appears that working for FAANGs is a "mark of distinction," these days. I know they pay ridiculous salaries. I'm pretty much aware of the working environment, and don't find the prospect enticing.
In NY, I know many, many folks that worked in the finance industry as brokers and traders. They got their licenses, and made a whole boatload of money in a few short years, while absolutely destroying their mental and physical health.
They then left, when they couldn't stand it anymore, and used the money they made to start companies, doing the things they liked doing.
Maybe that could be the approach the OP may want to take.
