It would be better if the bed were a bit deeper since right now the small distance front to back really limits what you can plant there to a single line of very narrow and probably small plants. With the relatively high porch and tall house, plants that reach as least as high as the porch floor will look best, and shrubs will be lowest maintenance. So having a larger planting space front to back will be the easiest to maintain. Are you willing/able to do that? I am thinking a minimum of 6' front to back, and perhaps swinging out on the right side to accommodate a small flowering tree such as one of the smaller crabapples or a variegated pagoda dogwood. At least one kind of evergreen shrub such as one of the smallest Thujas/arborvitaes and then either one flowering shrub such as a panicled hydrangea or a different evergreen would be nice, especially if you planted an evergreen groundcover under it. Just be sure that at its largest there will still be space behind the shrub(s) so there isn't rot on the porch from constant moisture; don't put in plants that fill the space initially since they will be too large in just a couple of years. 6 hours of afternoon sunlight, especially with the bright morning shade (no near buildings or overhanging trees) means that you most likely want to use sun plants. I like the generous width of the walkway and steps.

Could you please retake the pictures? Stand on the city walk, in line with the front door. Take 3 SLIGHTLY overlapping pictures that pan from left to right, including space beyond the ends of your house. (We'll see the neighboring houses as background.)

"Here is a straight on picture." It is straight on in the sense that you are pointing the camera at something and it will not photograph around corners! Other than that, it would be hard to call this a picture that is in line with the door ... or slightly overlapping pictures ... or 180*. This is a scheme for arranging, not one of specific plants. To get suggestions for what plants could make these shapes and sizes, you can take the picture to a local nursery or the regional forum that applies to your area.

The large bush on the right looks like a giant yew. Is it? You can bring the others (except the one on the far left) down in size, if you are willing to cut into them with a good hand clipper. Bring the down in size, but also create holes for sunlight to get in a allow for new growth. They will look awful for a time, but they will recover. In the left side, I can see a Japanese Maple. Plant it out from the corner of the house far enough for it to mature. It will frame the house. Create a circular bedding around it with mulch, lambs ear, ferns, and hostas. Then add two more yews to the newly pruned on under the picture window. Plant some perennials like Stella D'Oro Daylily, Cranesbill geranium, and Astilbe in front of the evergreen shrubs on both sides. Other plants to consider are hydrangeas. My two favorites are Oak Leaf and PG. Stella D'Oro Daylily: Cranesbill geranium:
