They don't exist. If you want out-of-the-box, use Jetbrains and pay for it. If you want free-as-in-beer, VSCode proper. For free-as-in-speech you'll spend hours to learn/configure neovim/helix/emacs, or even hunting down free VSCodium plugins, I guess.

I think working on out-of-the-box experience is not very attractive for volunteer contributors, so I guess the situation won't change unless we find a way to sponsor that work.
