Rocks retain water, so be careful about having it right up against the house. I would go to a local nursery. They should be able to suggest plant that will do well in your local. Look for a mix of evergreen and flowering shrubs, perennials and annuals with a variety of texture and heights. Plant well away from the foundation to allow the plant to grow to maturity at about a foot from the house. Look for a pretty ornamental tree to plant out in the yard in the middle of the left side of the house.

I'd plant a slim evergreen on the Left corner of the house.

2 large planters flanking the front door with colorful annuals (change out to something tall/spikey for holiday decorating) I wouldn't plant anything too tall in the upper level planter to avoid blocking the window, planting in rock gardens are tricky, keeping weeds out of rocks often too time consumong, but I would fill the lower with Native plants of interest.

You've done a great job, have fun!
