I also have this problem with Evernote taking up over 17GB of space across
Application Support > Evernote > resource-cache
Containers > com.evernote.Evernote
I've uninstalled Evernote and deleted the folders.
Afre re-installing Evernote and giving it a couple of hours to sync the folder in "Containers" did NOT re-appear and then "resource-cache" folder has re-appeared and is at 2.2GB.
So saved ~15GB, will see how this changes over time as I use Evernote
