One tactic to consider is fragment your identity into multiple profiles representing different facets of your life.

Your "work self", with your company's email address has one google account. When you leave the company, discard the account and create a new one for your new job.

Your "social self" who keeps in touch with friends and family has a separate browser profile just for facebook. There may or may not be an extra google account to go with your personal email address.

Your "privacy-nerd self" uses a completely separate email address unknown to either colleagues, friends or family, and a separate browser profile again which is only used over a VPN.

With network namespaces, you can even simultaneously run multiple VPN sessions, one per browser profile ...

And since your identity is fragmented, it doesn't matter too much if you have to burn one. The risk of losing data is distributed over multiple accounts.

that's a nice path. But what if you misstep and forget to enable the right vpn? You work and your social selves will get merged.

That could happen. So don't forget. Or don't worry so much.

A little personal responsibility and stoicism is called for; when you mess up, learn from the mistake and move on with your life.
