Not sure what affordable means, landscape and exterior renews are not cheap. Stucco often needs repair and you can labor for the landscape but the plants and dirt still cost ya. What is the budget?
I dont see any gutters on this house and some corners where water seems to gather and create staining, that would be the first thing to address. Second no matter what color you stucco it, it will still discolor, so I would invest in a power washer.
Or, skip the "affordable" make up fix and wait until you can side the whole thing. I would actually expand the front porch area,
