Have you tried OnlyOffice? It functions much more like MS Office, though I haven’t tried the features you’re talking about.

You could use SMSPool.

Yeah, you’re correct. Using Tor over (a trusted) VPN just helps with hiding the fact that you’re connected to Tor from your ISP. It won’t affect your privacy on the Tor network.

I recommend using iVPN or AirVPN (though I’ve had slowness issues with AirVPN).
