This may not be the best place to ask, but in looking at switching to Mullvad they offer something called Wire~~shark~~guard? I've seen ~~Wireshark~~ Wireguard mentioned a lot recently, but I have no idea what it does beyond a regular VPN or why I'd set Mullvad up on Wireguard?

I think you are mixing up Wireguard and Wireshark. They are totally different things. 

Wireshark is a network analyzer and it has absolutely nothing to do with VPNs.

There is no such thing as a "regular VPN". Wireguard is just one implementation, that happens to be pretty fasy and included in the Linux kernel.
