I only run Office 2019 Windows in a VirtualBox instance (Windows 10 Professsional) on one of my Macs.
I actually have a cheapass Wintel box running Windows 10 Home but I don't bother to run MS Office on that system.
Apart from MS Remote Desktop, I have no native Microsoft software on my Macs. No Mac Office, no Skype, no OneDrive, etc.
I am pretty sure I have no Microsoft apps on my iDevices.
Office 365 subscription which I use on MacOS, Windows and Android.
I use Mac, Windows, iOS, and web versions of Office365 every day. While there is a tremendous amount of grumbling around here about subscription based software, Microsoft is setting a great example of how that model can really improve the quality of software in the long run. Things are amazingly similar on all platforms.
