We used to use Confluence but it always felt too bloated and cluttered. It was a pain to get people to contribute and even harder to find stuff because of how slow and broken the search was.
We have since switched to Nuclino (https://www.nuclino.com/) and are pretty happy so far. Refreshingly simple, lightweight, and focused on getting the essential features right. We are now moving away from Google Docs as well and trying to consolidate all knowledge in Nuclino. It's almost perfect for our needs, only a few nice-to-have integrations are missing (and will hopefully be added soon).
Finding the right tool is only half the battle though, getting people to actually use it and keep the content up-to-date is usually the real challenge. Switching to a more user-friendly tool certainly helps, but it isn't enough to create a culture of documentation.
