I kinda agree with your point, and hate spending time organizing or following some "system" for my notes. Search is great, and is the thing that almost killed my paper notebook.
However, one feature I would really love to have but never seen, is a combined todo - notes app.
I often jot down notes as in "things to note / remember", but also, in the same flow, I'd note thinks I'd need to do. I would love to be able to gather those automatically in a view, and be able to see them as done when I revisit the initial note after marking them as such from the "todo view".
The closest I've seen was some VimWiki, but I've found that fairly unwieldy (though I love the idea of taking notes in vim).
I tried doing that (I pay for Obsidian Sync, and have a lot of plugins so I run only the bare minimum plugins I need on mobile), but app start time and syncing time on mobile makes this quite a bad experience. Instead, when I need to write something quickly, I create a temporary Google Keep note.
When I'm back at my laptop, I merge it into my Obsidian Vault.
I recommend LogSeq with Syncthing for your use case.
I'm using that right now for both TODO and notetaking. I have syncthing set up so that it syncs my vault across 3 devices (including my phone). Very easy to set up (tho admittedly also easy to mess up the set up process). Have had minor hiccups the past 5 months but nothing that would make me want to stop using this setup.
All this is free. I feel like I've found a gold mine that nobody else seems to know about.
I don't feel like learning emacs and trying to shoehorn vim mode (evil?) into it (vim-style editing is much too ingrained in my text-editing muscle-memory).
I understand that you do not want to leave your prefered editor but just wanted to sya that enabling Vim key-bindings with evil is a one line configuration. After that is feels native. I would not call it shoehorning at all.
