I would recommend to start with Wireguard, test it out with a VPS and one client computer before installing it for other family members on other computers.

Another tip, for enhanced comfort and ease of installation: most modern routers, even cheap travel routers, can function as a Wireguard client. So you could install an additional router, downstream of your main router, and create a wifi access point for your family, which tunnels all traffic to the VPS. The advantage is that you do not have to install wireguard on every client machine. You just install wireguard on the VPS, and you enter the wireguard keys and other config information in the wireguard config screen of the router.

At the same time you can leave your existing router running with wifi, so that your family can switch between censored and non-censored internet by simply switching from one to the other wifi access point. Why have both options? First, because non-tunneled internet will still be faster than tunneled internet (I guess), second, because some websites or government-run services in your country may only be available from within the country.
