How to develop a downloads page with filters

[ Moderator note: moved to Fixing WordPress. Please do not use Developing With WordPress for these topics. ]

Hi Everyone, I am developing a wordpress website for a client and they have a ton of docs to download from their downloads page. To make it easier to find relevant docs I would like to implement the option to filter on language and categories. I found a couple plugins but none of them really stand out. Does anyone have experience with this? I am open to any tips and or feedback, thanks in advance!
