By now you probably have something planted!
What do you like: perennials, annuals? Are you more formal or do you like a cottage garden? Your house looks older - I've a craftsman, my front beds have tall bearded iris, peonies, tulips, grape hyacinths, daffys, daylilies by either side of my steps. The rest is filled with annuals: I love Victoria blue salvia and always have nasturtium. I tend to use a lot of color not just one shade or family. I've also got a full width porch and do trough planters on my railings. There is so much you could do or try.
If you are looking for bushes: I love the look of a Red smokebush. However it may overtake the space. At my abode I have a varigated red twigged dogwood and magic carpet spirea (good for a mix of color).the dogwood also give visual interest in the winter. If you like fall color the Irish setter dogwood is nice too.
You have a fun house to experiment with. It's taken me a while to find what works at mine and it's been a bit of an ongoing study and experiment. Looking at magazines or even driving around looking at others plantings.
Sorry I'm not much help with specifics other than letting you know what I've found works for me and my area, what is available and in my price point. I guess that's all important too. I'd be interested in seeing what you have tried!
