One of the cuttings made it!
And I started having better luck with my ficus when I reduced water, and gave it partial shade at the hottest part of the day.
Indoors, I keep the lights on 16 hours per day and they usually grow for me over winter after a brief break.
Since I defoliated this one when I brought it in, it should leaf out, then chill for a few months, and be ready to get repotted in spring or summer.
