if I could pay a privacy fee to Alphabet and not be logged and data-mined, I’d do that.
It's called Google Workspace and it's decently nice. You can get a basic business starter account for something like ~$7 per month/per user + whatever you want to pay to register a domain each year. Takes a little bit of know how and you need to do some lifting for yourself that Google would otherwise shoulder for you, but it's pretty nice and has more benefits beyond just the privacy implications, like 30GB of account storage and Google Meet conferencing for up to 100 people without time limits. On the downside, some stuff that needs to track your usage to function properly (Like YouTube video recommendations) just do not work with a Workspace account because they don't track your preferences so they don't have a way to build a recommendation profile for you.
I've been doing it for years now and I appreciate it a lot. In the rare instances when I need to go do something on my old Gmail account it's shocking every time how bad the unpaid versions of Google products have gotten.
