I've edited the OP to show the stucco; it is located at the back and one side of the building, while the 2 exterior faces (corner lot) are brick. The brick wraps around the back and other side, slightly, before transitioning into stucco.

You haven’t said anything about budget. Change out the siding color starting from the colors in your brick. I would want something somewhat darker than the current color. I can’t see that adding cedar shingles to the top part of the gable ends, leaving the rest as it currently is, will be an improvement. Changing out the garage door for one with windows is a good idea. Match its color to the siding as the white highlights something that doesn’t need extra attention. Widen the walkway so that two people can walk abreast, and make it of more interesting material. Find a garden designer to help you come up with a garden design that suits both your taste and ability/interest in doing the needed maintenance. What you currently have has some evergreens which is good, but there isn’t anything interesting or that complements the architecture. You landscape is stuck in the 60’s with nothing except for your two rows of evergreens and a small patch of some type of flowers.

Here's a row of houses like the OP's: White, white (but with red headers - meh), and teal, which contrasts nicely. You can see that these houses all have red brick sides (if you look closely), but that it doesn't matter because they are so close together. OP, this is probably more the context the template architect assumed for your house. And then it seems the builder didn't adjust the exterior specs to account for the wide lot and sides being plainly visible, or the original owners reeeeally wanted that blond brick but couldn't afford to do the whole house in it, or it was assumed that other houses would be built closer to it, or something.

Everything there appears to be planted much too close to the house--and under the overhang as well. Also, any useful advice requires seeing the entire front of the house and a bit to each side. Zone and exposure important too.
