I would avoid diffenbachia (dumbcane), it is sold at almost every Lowes/HD and has quite noxious sap. Spathiphyllum and Aglanoema are good choices and are commonly available. If you do get plants from HD or Lowes, make sure to bare root the plants, wash them very well to remove any foliar fertilizers, and grow them out of the tank for a month or so (preferably longer) to let any residual systemic fertilizers dissipate. You may also want to consider doing a 10% bleach wash before introducing them into the viv.any other big leaf plants I might want to avoid that lowes sells?
Phalaenopsis should hold up to most tree frogs... the most they might do is break a flower stalk and even that would take them actually hanging on it a few times.I doubt it tree frogs are tough.
