Maybe the data connection, but not the radio that's listening for incoming calls (and it's periodically pinging the closest cell tower so that the cell network knows which cell tower to send that call to)

Location and traffic data still happen over wifi of course, so I wouldn't think that's considered "gone dark"

I was more thinking of data collection by cellphone companies, but what you've described can conceivably be done if you had cooperation from os vendors (apple/google).
Won't most phones being left at home generate no traffic because it's connected to wifi? AFAIK most phones turn off their mobile data connection if connected to wifi. It's also not too unreasonable to have very little baseline voice traffic, since everyone's texting these days. As for texts, it might be suspicious if you have a high baseline amount of texts, but it's also not too unreasonable for someone to communicate almost exclusively using chat apps (eg. signal, imessage).
