vim generally doesn't need any of those fuzzy file finders that most people use. If you add

  set path+=**

to your vimrc, and open vim from the top level directory for your project :find <unique_filename_part> will just work

Setting up ctags will give vim some IntelliSense-like functionality that people tend to miss from their IDEs. More info here: https://andrewra.dev/2011/06/08/vim-and-ctags/
