What is the best way to tile the same material on objects with varying sizes?

I've seen this question asked in other posts but haven't found a good answer so far. See attached photo for reference. (Note: this is a 2d top-down game in a 3d environment)

I have a parameter around my scene. I want this parameter to have the same texture all around. My first thought was to create some quads for each of the wall sides, but obviously the texture was scaling according to the quad size, thus becoming distorted. So then I decided to create individual "wall" units as cubes and just repeat them all around my parameter.

My question is: Is this the best and most efficient way to do this? And by efficient I mean both in terms of practice and game performance. I'm wondering if these many cubes, all with the same texture, will eat up more resources compared to having larger single-object "sides" with some other (unknown) way of applying/tiling the texture, and it looking consistent no matter the size of the object.
