I would say it would be similar to Google from the early-ish 2000's. Lots of offices worldwide to facilitate in-office working and immigration issues, while also having freedom to work remotely if desired. Also, a structure that leads with empathy, and managers judged on not just output but employee happiness.

There was a lot of freedom in big tech over the last few years. I could transfer pretty much worldwide within a month, I could work on several different moonshot industries with no worry of losing my job (because I'd just transfer to another team), and the market was good enough that if push came to shove I could take some time off and find a new role with minimal issues. I think an employee focused company would keep that freedom, while also keeping employees happy and without fearing for their job.
