The 4 most important things for stripping Google out of your life are:

1. Your phone (Location and Internet usage)
2. Your browser (Internet history)
3. Gmail (intimate details of your life)
4. Google Login (federates your identity across their Ad business and tracks your search history)

Everything else is nice to have, but not as “signal generating”.

Remove those and set your Google History to 30 days in your account settings and Google loses a lot of your identity really fast.
