> Now it looks like office 365 is going to be the cloud editing future for word / excel type needs

You are in for a surprise. Office 365 (at least Excel and Word) looks like a toy compared to the desktop versions. I'm not talking about niche features or VBA, I'm talking about things like naming a table, which is explicitly only supported in the desktop version. Ah, of course! You need the table's name to use it in their Power Automate platform. Microsoft 365 is a mess right now. I hope it improves.
