I think the usual advice is to try the vanilla Emacs, maybe use better-defaults (either directly or just for inspiration), as it is a relatively light customization. The setups people use tend to be quite different, as do their opinions on packages, so I doubt there is a single satisfactory and agreed upon "source of truth". Others' setups may be useful to check out, possibly pages of emacswiki.org, chatter on the #emacs IRC channel at libera.chat.
Edit: As for heavily customized versions (Doom, spacemacs), I have not tried those myself, but occasionally saw people having issues with those, and others not being able to help them, since it was not clear what sort of magic is going on there. So I would not recommend those to new users, at least not if you would like to learn the basics and get a better hang of it, to be able to debug it, though some seem to be happy with those.
I will second the recommendation to start with vanilla emacs. That isn't to disparage releases like spacemacs & doom. I simply found those to be more useful once I fully understood the power that comes with a fully reprogrammable editor. There is a learning curve and there is also a mental model to adopt, and I think that adopting the mental model is easier when starting raw and building up from scratch. Once you feel comfortable maybe try spacemacs or doom to see if they offer advantages for your workflow.
