Google Workspace looks like the best option. Decent plus is that I'm already using a Google account for a lot of things except email. Main concern I had (forgot to include in original post) was calendar. I use iCloud+Calendar.app for calendar (and basically nothing else), and my existing Google account doesn't play too well with it. Figure I could mostly mitigate this by looking into other calendar clients (Notion Calendar works with Google which is a plus).
