I use lazyvim and you're still going to be configuring a _lot_ of stuff by hand with it. It's really just a framework for configuring neovim with an opinionated file structure. Compared to other neovim plugin 'distributions' this one is pretty hands off as far as out of the box config--it really just has the bare minimum to get popular language LSPs up, and a lot of missing LSP features that neovim hasn't implemented yet (like autocompletions). For everything else, like defining your own little shortcuts and commands, it's wide open and up to you to figure out just like regular neovim.
Basically this distro is useful if you want to play with neovim plugins but don't want to spend days surveying the landscape to see what are the most popular and usable plugins... lazyvim is doing that for you. As far as using neovim goes this doesn't do much and it's still up to you to do the work to learn and configure it.
Probably what I like about my NeoVim setup (an organic, home-grown completely from scratch mess of .vim and .lua files) the most is universal containerized language server for any project.
It gets me go to definition, peek definition, etc. in TypeScript, Python and probably anything else LSP-compatible without polluting my main machine with any of those development environments and only requires Docker.
The editor detects a special INI file in project directory and launches a Docker container that runs a language server. The INI file can specify a common Dockerfile (works for zero-install Yarn where it mounts repository root as read-only volume and just works(tm)) or a project-specific Dockerfile that does some system setup (useful in case of complex Python/Django backends, for example).
I’d be curious to try a configuration like LazyVim if it supported something like that out of the box, but last time I checked most of these were written in mind with LSP running directly on your host.
