I use Obsidian these days, I found the switch from Apple Notes pain free. I still think Apple Notes is a great app for almost everyone. Not perfect but really good.
I went this way as well. I used to try and make all my notes in Notion. But found the lack of offline support and the mobile app very limiting. Then I tried Apple Notes with a framework called "Forever Notes". Obsidian does everything Forever Notes does but better.
