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.
