I use different editors for different purposes, e.g., Obsidian for long form and planning, OneNote for meetings.
I wouldn't overthink it, though, and just use the simplest tools available. I use Sublime Text 3 with a few shortcuts to add the current timestamp, etc. and log everything in a long file. I was too ambitious in the past and wanted to learn how to use Emacs for everything, but it just held me back, and I ended up without any notes.
I usually don't move notes to and from OneNote. I tried this Obsydian importer, and it is OK for my meeting notes in terms of formatting. However, it has a bug that strips slashes from page titles, which is a bit of an issue for me because I always add dates to titles (e.g., 7/13/2024).
With a few good examples, maybe some LLM could help you with reformatting?
