WireGuard is great and is not too difficult to setup on something like a RPi. I have one running on my home network which lets me access my local network remotely, including access to my local media server. I have another one running at my parents' house for times when I need to RDS into their windows machines for troubleshooting, or if I need to tweak settings on their router. You can also configure your clients (phone, laptop) to forward all traffic through the tunnel, which then secures your connection for when you're over an untrusted/public wifi.
