Look, I read about half way down and went near apoplectic...
For I am the mighty groundhog, terrarium horticulturist extraordinaire
(I also tease alot
Seriously:
1) Personally, I would not put any nice plant in a tank with herbivores, other than their recommended food;
2) Asclepiads: Are fine. Hoyas and Dischidias can rot if overwatered, but are not dangerous--sheesh...
3) Aroids: Are fine. If you must plant with omnivore/herbivores, then stay bioopical. In other words, philodendrons, anthuriums with iguanids (new world), Epipremnum with Corucias (old world)...
(Seriously--

--I humbly believe only a %^$&* fool plants valuable plant material with vegetarians...)
4) Why biotopical? Because organisms evolve in tandem. This is why one cannot expose bearded dragons to English ivy--it will kill them. Conversely, it is why iguanas laugh at
Dieffenbachia, or why rabbits and deer can eat poison ivy...
5) Euphorbiaceae: Are--you guessed it--fine. They are in fact highly recommended for setups with east or south African lizards (e.g., agamines, skinks, cordylids).
*And poinsettias, btw, can't do s_____ to new world herbivores...
**if you are worried about Uromastyx, read a %#^&*@ Uro book. Again, why the $%#^@ would ANYONE plant valuable plants with Uromastyx?!?
6) Virtually all Acanths, Begonias, Gesneriaceae, Moraceae (Ficus), Urticaceae (Pileas), bromeliads, gingers, marantas and orchids---ARE FINE!!!! (This means no dumbass questions about bromeliads with spines on their leaves...okay, do not use genus
Bromelia)
7) Which brings us to cacti: Here, I do concede that there can be mechanical damage from spines in relatively small spaces. But the real reason we do not recommend cacti for desert setups is because we usually cannot provide the blazing high light. For "American" setups, small agave- types, sedum, sempervivum and Yucca-type plants are usually easier.
Hope this helps.
