I'm not sure how close can it get, but ONLYOFFICE products have been good to me so far. AGLPv3, good docx / xlsx compatibility, free for personal and there are paid business plans.
I've seen ONLYOFFICE used on Nextcloud instances and I haven't seen Google Analytics loaded up. Do they provided a cloud/hosted version that has it? But agreed - I was impressed with ONLYOFFICE.
They have lots of different offerings. I looked at personal.onlyoffice.com, their free hosted version for personal usage, and they load Google Analytics not just on the landing page, but when you open a document as well.
