Regardless of whether this is a situation you'll ever find yourself in, there is an all too obvious design option that exists, one that meets all of these criteria -- and should also meet budgetary demands as well. What is that option? As is so often the case, the answer can be found in some of the great historical basilicas of Christendom -- namely, the use of polychrome marble revetments set into simple geometric patterns.
Designs such as these characterize the great Roman basilicas in general, including those found in the East in places such as Constantinople. They involve the use of coloured slabs of marble that utilize very basic geometric shapes: circles, ovals, rectangles and so on. It sounds very simple and that is because it is -- and yet the effect is one of great beauty.
Too often since the nineteenth century we've become fixated on placing images and complicated designs on most anything. These have a place of course and when done well, they can be extremely edifying, so to be clear, I am not advocating this be abandoned; I am simply highlighting another option to consider.
Let's take a look a few examples coming from different centuries -- and as you'll see, the century really doesn't matter as there is a certain timelessness to these designs (which is exactly what you want in my estimation).
