I've been using Linux on and off for years and I've never really understood what these different directories are for. If I don't know where something is I just search for it, though more often than not whatever I'm looking for is somewhere in the home directory. I'm also not sure of the accuracy of this though. I have a VM in /run, and an SSD and thumb drive in /media. I would've expected these to be in /mnt.
