Those should all be possible, particularly if you use Core. (More about that later.) i’ll leave the specifics Sonos discussion for people who are currently using it, I don’t have them.
At my house, we use a Phillips hue light strip specifically for arrival notifications. My housemate plays videogames and we’ve discovered he doesn’t answer texts when he’s playing. I’m a wheelchair user, and in really bad weather I can get stuck in the yard. So the light strip turned blue when I enter the front gate (just me, nobody else). Once I’m inside the house, I tell echo to turn the light off again. So if it turns blue and stays blue for a while, he knows I’m stuck in the yard and will come out to help me. It’s a system that works well for us when hardly anything else did!
You might find the following thread of interest as well, it discusses several projects that might be helpful.

And Here’s more about core:
