Well, if you want plants, Africat Cichlids are out. You know, Mbuna, etc. But you can do Dwarf Cichlids, Angel Fish, those types of Cichlids. All of those work well in a planted community.
You could do
1 Pair Rams (Bottom)
8 or so Cory Cats (Bottom
15 Cardinal Tetras (Middle)
15 RummyNose Tetras (Middle
15 Hatchet Fish (Top)
or
1 Pair Angel Fish (mid-top)
15 Larger Bodied Tetras - Cardinal, Rummy, Emperor, Lemon, X-Ray, Penguin, etc
15 Larger Bodied Rasboras - Harlequin, Siccortail, etc. (Sorry that's all I can think of, I am more of a micro rasbora person!)
1 Pleco
or substitute one of the schools for Cherry Barbs
