Can definitely recommend at least trying structurizr. I'd recommend starting with structurizr-lite, which runs locally on docker and version controlling your work as you go.
Just starting to use it myself to document an existing system that few people understand and there is not a lot of existing reliable knowledge of. Doing this sort of task has so many benefits long term but can be painful in terms of getting started.
The combination of C4 approach, structurizr for diagrams, embedded markdown for detailed notes and version control is feeling like a great combination.
Having it version controlled helps a lot with collaboration and communication. I'm using PRs in order to get insights and corrections from others without the need for constant meetings/discussions.
