No worries at all, glad it may have helped. Given what you recently said I'd suggest looking into threat modeling. It's specific per person and can help you decide what you want to keep private along with who you're wanting to avoid.
My take away from your post is its general privacy and maybe surveillance capitalism - big tech and all the unknown ad companies following us around the internet.
Anyway, once you decide your threat model, its easy to use isolated accounts or burner accounts (even if its google) for what you want to accomplish. You just have to taken some extra steps to keep private sometimes.
The worst you can do is think you have to avoid everything (like Google) because it's used by some agency to monitor you, or be concerned about being hit with Pegasus etc. Yes some people need that level of privacy, like whistleblowers, journalists or lawyers to name a few. But that's not what everyone needs. You don't want to get overwhelmed.
Cheers
