There are so many considerations, soil, amount of sun, what look are you aiming for, budget, etc.

We took a picture and headed to a large nursery (during their low period) and they provided all kinds of suggestions for free (they assume you will be buying from them, which we did).

Hostas, shrubs that keep leaves all year, different green shades, cedars, and height variations especially under the smaller window.

Might be nice to address trees as well.

Please step back and get a better picture of the front of the house. Do you want to keep that tree?

I'd get rid of the tree blocking the view to the front door.
