If you already use emacs I'd recommend checking out org roam. I've used it a bit prior to switching* to obsidian, it worked well.

* I didn't switch due to any issue in org roam itself. I was curious about obsidian since I kept hearing about it and also I occasionally use windows and am not a fan of the emacs experience on windows (slow, configuration sharing issues).
