That's exactly my problem. After using all these apps I am having hard time routing these into one app and my lists are scattered across different apps. I wish there was a painless and easy way to jolt and knowing it would end up in my master Todo list. But instead I have to think which app list i should be using...
I've been using Omnifocus for to track Todo items and Apple Notes for taking notes. Both sync across all my devices. This has been working really great. Before the pandemic I used physical notebooks to take notes during meetings because it made it obvious to others that I was paying attention to them and valuing what they are saying rather than slacking with someone else. That led to the integration problems you describe and I needed to spend 15 minutes every day syncing things. Arguably that also was a valuable review time that sometimes led to new insights.
I’ve stuck with vimwiki + fuzzy finding for years and it’s worked without any issues. If you’re into vim based tools, and haven’t tried it, I recommend checking it out.
I'm not big into using my phone for notes. I'll put random stuff in Bear or Apple notes but I take my computer everywhere so I just use that for the wiki.
Although obsidian would also work well with fuzzy finding since it stores markdown files locally. For any rough edges, you could write a Lua plugin for neovim, if you want fully featured vim (I tried out the Obsidian vim mode but it doesn't seem to be feature complete).
