The OP may have better ideas, having succeeded already in different setups but in my opinion in monster tanks one can concentrate on keeping only emersed plants. I pot mine in hanging plastic baskets, drilled with holes for water exchange and filled with clay pebbles. So generally the roots are protected and unless fish can fly, they can't get to them. My filters' flow is normally aimed at passing above the baskets surface.Most monster fish tanks have no plants or scape, just a few ugly flower pots. The OP always has plants and scape, just check out his historical setups in the East Coast. I don't know how he can manage protecting the plants from the fish, as I am struggling with mine.
Here are the ones above my indoor pond.
My planters are plastic black baskets with a hanger but I am sure there are all types of options suitable for glass tanks too.
Emersed plants are extremely efficient at maintaining water quality and give that extra level of redundancy. One would notice healthier and longer lived fish in tank setups like that. It is so worth a try and it is beautiful inside one's home if they've got the space.
