Brand new homes seldom have much in the way of impressive landscaping unless they are high-end, custom builds. Developers/builders buy small, common and cheap! And your new home is just too new to have the plantings make much of an impact.

There are various ways to approach this, including hiring a design consultant (often a valuable investment in establishing an appropriate landscape) but one of the easiest and cheapest methods is to drive around established gardens in the area and see what looks good to you and what you admire. Take good, clear photos of the plants and post back here for ID's.

Pay close attention to the size of the type of plantings you like - that bed is not all that large plus you have windows on that one face that you probably do not wish to block - so look at smaller, more compact forms. Some things to consider are dwarf conifers, compact or dwarf forms of broadleaved evergreen shrubs (abelia, dwarf rhodies or azaleas, nandina, etc) potentilla, compact spirea and barberries, and heaths or heathers. You might even be able to include a small Japanese maple in the larger part of the bed if you wish.

I'd bring the lawn up to the walk - at least in the area to the right of the lids.

The dark green evergreens are planted too close to the cement--one could be moved to nearer the fence--should be 3 or4 feet away from all structures.

Unless you like the look of last year's dead ornamental grass, cut those down before doing so interferes with new growth.

Hard to advise further without knowing your general preferences: shrubs/trees/fruit/flowers/time.

Not sure what your idea of hodge-podge is. This might be exactly what you mean, but I think it would look terrific with what I can see of your home. It's a mix of sun loving perennials, which are often more affordable than some shrubs, although a mixture of both keeps it looking better in the winter when the perennials die back. You could find pics of things you like and take to any good size local nursery for help with i.d. of pictured plants. Some you might find at big box stores, but I prefer the quality and personal (educated/experienced) help at local nurseries.

This is a little more orderly, if that's what you prefer with some pretty common plants and a nice mix of shapes, colors and textures:

And after my disclaimer about big box stores, I found this from Lowes that might give you some ideas. It's not very interesting to me, but very orderly, and if you aren't really interested in gardening and upkeep, it might be fine:

ETA: I just found this and like the idea of adding seasonal pots to fill in, (although you have to keep up with watering them well) esp. until your other plants get established.

What is better about the last picture is that there is some repetition of kinds, which reduces the appearance of spottiness produced by planting only one of each - if the other schemes (the second one in particular) had drifts of multiple examples of the same kind where there is instead a single specimen they would be a hundred times more effective.
