I also switched from Vim to Emacs specifically for Org Mode and Magit. I found the Doom Emacs configuration to be a perfect match for my muscle memory. ;)

I document my learnings about the Emacs/Doom ecosystem (including Org Mode, Magit et al) in a form of short videos on YouTube [1]. Maybe it will help in your journey...
