Coral honeysuckle does require a sturdy trellis. I have two Dropmore and Major Wheeler that are on sturdy trellis one is wood and the other is metal. The nice thing about these honeysuckle is that they blooms for a long time attracting hummingbirds and they take trimming very well and are easy to take care. I am not familiar with your climate but here they require watering to get them established, now mine do not get extra water other than rain.
I agree about trumpet vines, don't plant them they will want to take over your house and grow all over your yard far from the original plant.
