I can't help but think there's something inherently wrong with #logseq. There's a heavy abstraction layer on top of markdown and as a result, your files are barely usable without the app. Why not use something like sqlite at that point? They made an awful compromise and ended up with something that is neither markdown nor a real DB.
On the other hand, #obsidian is clunkier, but I can open my folder in a text editor and not drown in irrelevant metadata and generated ids.
If you perform a t>o shortcut on a page you can expand all blocks, the collapsed:: true properties are removed from Markdown files.
The other metadata property I'm aware of is heading:: true for auto-heading but I use that only for pages serving as indexes.
The rest is properties the user adds intentionally.
