FZF-like way to quickly change into a directory? Include hidden files in Vim FZF?

I am looking for a way to quickly change my Vim directory to a directory I find through an FZF-type-of-way. I understand it stands for Fuzzy File Searcher, not Fuzzy Directory Searcher, but I'm sure there is a similar tool or a hidden feature to use and benefit from switching directories so fast.

Example: Directory I want to go to: ~/Notes/Class 1/04-24-2020

What I'd like to type:

:FZF class 1 04 24

Thanks in advance!

Bonus question: How would I include hidden directories into this? If I would like to edit my init.vim configuration file that's hidden in .config, how would I pass an argument that would include that?

EDIT: Answer to bonus question written out below.

Found the answer for "including hidden files".

In the example below, I am using fdfind. Feel free to use anything you'd like!

command! -nargs=? -complete=dir AF
  \ call fzf#run(fzf#wrap(fzf#vim#with_preview({
  \   'source': 'fdfind --type f --hidden --follow --exclude .git --no-ignore . '.expand(<q-args>)
  \ })))

You'll do fine with the code above, but if you're looking for a more meaty configuration addition, here you go:

" Terminal buffer options for fzf
autocmd! FileType fzf
autocmd  FileType fzf set noshowmode noruler nonu
