There’s (arguably) an argument to be made that Emacs configuration distributions fit that niche - Doom Emacs, Spacemacs, and Prelude provide varying flavours for different kinds of Emacs users.
Apart from that, I don’t really know what an application would be to Emacs as nvim is to Vim. It’s more like nvim is to Vim what Emacs is to nano, except Emacs came first.
