How far back are you thinking?? At least you have a really nice retaining wall. I'm one of those that would plunk in a couple of flowering shrubs, put down weed barrier and mulch the hell out of it. LOL I just really like the look of mulch.
I'd plant some of these bushes at the far back of the property area and then add some semi-shade loving plants in front of it. Paint some stepping stones to match (like I did in the photo) to make a path that meanders along that area. Hostas would look nice in there too.

I like the Blue Rug Juniper; I planted that on a much smaller slope and was very happy with it. I planted spring flowering bulbs in between for some occasional color.
One site I like to look at to get ideas is called Stepables. I look to see what the plants look like when they mature then I make my purchase of local plants that will grow well here. https://www.stepables.com/3/ST...
