CGNAT = Carrier Grade Network Address Translation. It makes it practically impossible to open ports to the public internet and in some extreme instances make zerotier very unstable. Typically you only have CGNAT if your internet connection is 4G or fixed wireless.
OpenVPN is just a VPN protocol. Roughly comparable to wireguard. It has been the gold standard for VPN technology for the past decade or so. Wireguard by comparison is much newer, and lighter to run. This typically results in faster throughput from a computational standpoint and devices where power is limited (cell phones), uses much less power by leveraging modern CPU encryption methods.
If you have the option to port forward on your home internet connection, its possible to setup a VPN connecting in a straight shot from your home to your roaming device. If you can’t port forward, you will need a main in the middle (the VPS) to establish and route the connections through.
Zerotier works off of a PTP style network and the free plan allows up to 50 devices when last I checked. I’m not sure on the availability of zerotier or wireguard on truenas as the last time I used TrueNAS was Scale 22.

My provider uses CGNAT in AUS and I’m on fiber then copper connection. Luckily they just had a option on their account page to turn it off.
Btw, Tailscale raised the free tier limits a while ago and it’s now an even more generous 100 devices/3 users
