No doubt some of them were terraced. I've never succeeded in keeping
anything terraced for any length of time, so maybe someone who is
successful with it can explain how they did it.

In my experience most plants seek out and thrive with an anaerobic
substrate. Just the same, there are limits. I wouldn't want all of the
substrate to be anaerobic.

Some plants (Bolbitis in particular) don't seem to attach well to
rocks. Wood works better. I would stay away from foam plastics like
styrofoam; that's partly because they release plasticizers into the
water and partly because a lot of the foam I've seen submersed very long
appears to degrade. I seem to recall that one of the large tanks in the
2000 AGA contest had a construction on the back and sides that appears
to be of styrofoam or something similar.

I'm glad you're happy with your tank. Lack of CO2 and sparing
fertilizer may be why the lower leaves of your stem plants look a little
ratty. Those factors (taken together) keep the lower leaves on stem
plants looking better than they would otherwise.
A common practice is to stagger the height of plants from high in back
to low in front so that plants at the front obscure the lower leaves on
the background plants. That way the lower leaves on the background
plants can get pretty ratty and no one notices.
