This was one of my biggest issues, but I did manage to succesfully switch to nvim few months ago, by installing ideavim into Rider, vscode-vim into vscode (so I can't easily escape it when I get lazy), but most importantly - setting LazyVim as my default editor, which has been a lifesaver.

It has a pretty good LazyExtras interface for easily installing a ton of plugins, almost for every language. You just open the LazyVim menu, select a language you want, and it installs LSPs, debuggers and whatnot you may need for it. It's probably using the nvim-lspconfig mentioned in other comments, but it has been pretty seamless.

But any other pre-made nvim config will work, this one is just more approachable than someone's random plugin list.
