if you don't like the three dimensionality of hanging roots, or floating stem plants, something like vallisneria allowed to grow up and across the surface could be an option
I agree this (the T5 NO) should work. Given that T5 is more efficient than T8, it is likely that a bit more light output is occurring, but not so much that it can't be managed. So that leads me back to my comment on regular dosing of nutrients. Any irregularity can create these opportunities for algae.
On the floating, my personal favourite is Water Sprite. If allowed to spread, it can very effectively darken the tank. But it is easy to keep it in balance, by removing the largest/larger plants during the water change and allowing the smaller to grow, then next week or the week following, same thinning process.
