Notion.so is relatively new web service that is sort of like Google Docs/Sheets/Sites/Trello baked into one thing: very flexible, modular. Not as spreadsheets-on-steroids as Airtable is (which also has recent upgrades for EDU address), but really, in my view, can give you flexibility in developing content for the classroom.
I haven’t started sketching it out for the team setting, but could be a viable option. Also, trying to understand how you could have multiple people work on it without paying up for the Team plan. At the very least, it could be a knowledge base for the team and maybe give edit-privileges to certain members.
Can export to Markdown/HTML.
Free for everyone. EDU gets a little more function.
I recorded a four-part series (under 45 min total) to start from complete beginner. They have tons of templates and many software companies are using it now https://www.youtube.com/playlist?list=PLh3iFL9dzjQSK9svoX_xvMbguGR_yFeLx
