I would avoid Bronze aka "Tropica" it grows more compact than the others but Red aka "Mi Oya" and Florida sunset both grow taller with longer petiola's and leaves especially if they are shaded a little.
There are certain crypt species that grow tall like jungle Val such as crypt spiralis and crypt balansae. I would use the wendtii as more of like a background plant depending on what size tank you have
depends on the size of the tank and what kind of substrate you have. i have noticed that my dwarf sag tends to stay shorter in gravel than it does in sand not sure y. this is my 29 and the tall plant in the back is ole red ( red crypt i think that is how you spell it) and dwarf sag in the middle
