It is less simple than discord and I does not have good audio rooms. I setup family accounts and store their security key for them. Then I help them setup their app in a few minutes and paste them their security key once they are on my matrix server. In the past I left sign up and setup to family and the element app and it has never worked smoothly. They don't understand the security key purpose or verifying clients. So to answer your first question, yeah you can invite grandma and grandpa but they probably will need some hand holding at the start. Once they are in, it just works™**. YMMV
