My parents, in-laws, grandmother-in-law, and entire extended family is on Signal. It's the extended family group chat, video calls with grandparents/great grandparents, and the baby photo feed. That's mostly because you just install it and it works.

I have no idea how to get my extended family on a Matrix homeserver without extensive handholding. I can barely figure it out myself and I was a huge XMPP nerd that ran my own ejabberd server for years.
