Some rendering programs like Kerky(Thea) will allow you to adjust the UV of each material in how they project.
I know that VRay in 3DS-Max will allow even greater control, and you can bring that to the next level with UVW Unwrapping.

If you are using a simple program that will let you set up a basic wood material:
If you assign different material colors to you objects, then in the renderer you can assign different grain directions and wood types to each material instance.

For instance: all the long-board panels would have a material that has the grain going vertical, and the trim would have more custom arrangements.
I have a feeling that if the UV of the arched trim you have at the top follows the curvature of that piece, and perhaps the material would follow.

I say, break it down like that and do some experimenting.
