Personally, I share your reservations about anything Google, but according to what I found with a DuckDuckGo search, G-Suite is changing to Google Workspace and email is just the tip of the iceberg. It is a complete suite of communications tools including calendar, addressbook, email, text messaging, on-line meetings, and works best with Google Chrome (which is not surprising).
this How-to Geek article does a good job of explaining G-suite and its successor Workspace.
This article has a reasonably complete set of customer reviews. As there are a number of Workspace plans (and prices) you might want to ask your ISP what Workspace features are included in what you will be getting.
An alternative you might consider as an Apple user, is Apple. I have used Apple as my primary email provider since its first inception and while there were glitches early on, it has been rock solid stable for several years now and is FREE.
