Mosses, java ferns, bolbitis, anubias and bucephalandra (buce) are all great low light, easy plants that will grow on the wood. For tall substrate plants there are many options. PFS is inert and has no nutrients of course. You can use root tabs to compensate but I would avoid heavy root feeders like swords and crypts just to makes things easier. With this big tank it would be difficult to get the tabs down in the substrate, in the back of the tank, behind all that hardscape, no? Look for easy stem plants instead. Pennywort and wisteria are super easy, grow tall and/or busy as well plus I find them very pretty.
