I've had the best luck in low light with the monkey puzzle tree (containerized it doesn't get too big - but outdoors 80 to 100 feet tall??) Also called Bunya Bunya. A friend put me onto this years ago. BUT it is extremely sharp needled and takes up a wider space.
The family of Dracenas should work but you might want to give them a break from the low light now and then - rotate. (maybe the Janet Craig Dracena could tolerate the lower light for a longer period.) Or a standard Schefflera.
There are some cultivars of Ficus that will tolerate lower light than others. It's been too long for me to remember which without looking them up.
You might consider using a plant stand to raise the height of a trailing plant like heart-leaf ivy, pothos, cissus ..... I've done this in a couple places and been satisfied - especially if you can find one with some good long trails.
Remember to acclimate whatever you get gradually to its new low light environment, especially if it has come from a brighter greenhouse.
Good luck
