Looking for a Note-Taking App, migrating from OneNote, any creative ideas?

Hi,
I’m a few months in from moving away from Microsoft Products, but I’m stuck on OneNote. I like how it organizes things. I’m looking for a solution that has a web / cloud version, Linux App, and Android App and hopefully a migration path. I found a script here on Github that exports all my OneNote data to a format for Joplin. I like Joplin, but it lacks the web version, and a few other options that I need.

Is there anything I can do to export all my data from OneNote in a similar file structure and view/edit on an Android app, Linux Machine, an the web?

Any suggestions would be very much appreciated.
