I think I made a similar move about 6 years ago now. Started on Doom Emacs for the first 2-3 years, and honestly, for most users I think Doom Emacs is all you'll ever need. If you ever decide you want a bit more control over your config, which is what the case was for me, then it maybe makes sense to start writing your own configuration and learning about more of the native features. Would definitely recommend system crafters' emacs from scratch series that others have linked here -- extremely helpful.
