Your list of success is pretty much the list which works for most golds. Crypts are good...I have used about every species of crypt with golds and none have been bothered. Some floating species work well...they just outgrow what the golds can eat. Frogbit is awesome for this and it gives them some plant matter in their diet. Apon. crispus works as well....its tough as nails though.
One thing that also helps curb golds tendency to go after your plants is feeding foods high in vegetable content....I feed Hikari Sinking Cichlid Excel, Cobalt Spirulina flakes, and Emerald Entree Frozen.
