Help! Hedge/screening plants that can grow evenly in sun and shade (if that’s a thing)

I’m looking to plant hedge or screening plants behind a new fence. My experience has been with what I think is pittosporum, where the side that faces the house gets nice sunlight and is relatively dense, while the side facing the street is shaded by council trees. The side facing the street is sparse and ugly.

The pittosporum grows well in height so is getting the light it needs, but it’s the street facing side that is the biggest concern. I’m considering both sweet vibernum or lily pilly but I’m worried I’ll run into the same problem.

Anyone had experience with this and found a solution?
