Alyssa, what a nice find! That healthy
Balfour Aralia (Polyscias scutellaria 'Fabian') has a really nice looking trunk!
Repotting can sometimes cause stress and this time of year might not be the best time to make any changes. The adjustment of going from a nursery situation to a home with even slightly different lighting, humidity, etc. may be be a cause of stress. I'd leave it as is and just place it into a heavier, more decorative container ... maybe consider potting up one size next spring when the weather warms.
I had one with the solid green leaves years ago but now only grow the one with white leaf margins.
