I don't know about where you live, but by far the lowest latency option for me is symmetric gigabit. And my options jump from 200/20 to 1000/1000, and 200/20 was for sure not enough for everyone to stream and video chat at the same time.
It surprised me, but it works. And despite my 1125/50 connection at home, it surprised me how easy it was to adapt to lower speeds.
That being said, given the option I'd say 200/20 is my preferred minimum.
