I also rely on Markdown files and typically write very short content in each file, especially to help with my memory. I tried Google Keep, Evernote and at some point pain-stakingly migrated all the notes I had to Notion, but they are missing "something" I don't know yet so I regressed back to markdown files in a directory.
I created a tool to automatically structure files into a directory tree based on file dates because of this: github.com/zikani03/groupby
It is really great to see more attention given to this space. That and personal relationship management tools (e.g. Monica)
I think the something missing in Notion is keyboard shortcuts and overall feeling that it does not feel fast enough. For example navigating to a page and then jumping between pages requires more steps than I am comfortable.
Sounds like your writing style fits with how TiddlyWiki[0] works. I just started using it, but like it so far. Has a plug-in for editing in Markdown as well.
