Best compromise is a markdown file. You can read with it with Obsidian if you want a better gui, but you can also just treat it like a simple text file if you prefer. No lock-in to an app.

I agree that complex todo apps are a bit of a waste of time.

Markdown + Vim-wiki plugin is a really powerful combo, that is still all only markdown underneath.

And yes, you can combine that with something like Obsididan at any time.
