Honestly that is all you should ever use these VPN services for. Convenient access to blocked content (or flip to a different region to access alternative content).
Sure your own VPS running WireGuard or OpenVPN is better but that isn't as easy as just picking a different country on a pretty map in an app to get access to a show on BBC iPlayer or Netflix a second later.
Nord, Express, etc. are close to worthless from a privacy aspect but they're very convenient for watching blocked content and that is all anyone should use them for.
If you want/need privacy because you're on a network you don't trust (hotel, airport, whatever) then your own VPS and WireGuard are what you should be looking into. If you trust you home ISP and have decent bandwidth (both ways) you can easily run your own WireGuard server on pretty much anything from home and just connect into that so cost is pretty much zero.
