What's a good alternative that has a web client at least when you are on desktop + you can video call too?
You can pay $10/month for your own Modular.im Matrix server host and use that with your family (it also funds the devs).
They have Jitsi support for video (you can also just use Jitsi stand alone).
I think signal also has video calling, but not sure about group call support.
Both have mobile and desktop apps. Both are encrypted and ad free. Matrix is federated, but modular.im makes setup easy.
