A bit late of a reply, but, to me, wireguard is more of a catchall solution, where as zerotier focuses on one job, accessing internal services externally. Zerotier seems like a fine tool, but I feel like learning how to use wireguard has more opportunity to come in handy later. Not to mention how wireguard is a part of the kernel now, which makes things a bit more convenient as well.
