I don't have any problems with using cast iron pans on my ceramic hob, although I've yet to try the griddle (which doubles as a baking stone). Just make sure your pans are all suitable for use on a ceramic hob.
The only problem I have found is that the rings on it are not the same sizes as my pans, and of course one of the rings I use most is right over the back, while one of the front ones I rarely use at all except when I'm making cheese or yoghurt, which are usually the only times I use a pan of that size. It couldn't be turned round because then I would have to reach over some of the pans to use the knobs. I also have to remember that it heats up a lot quicker than my old electric hob, and retains heat for a lot longer, and I've had to re-think the way I cook some foods (especially rice and milk-based sauces). It's very easy to clean and keep clean. I have a suitable metal scraper for any burnt on "disasters", but for the occasional "accident" an old credit card works perfectly
My daughter has a ceramic induction hob, which with hindsight I think I might have preferred as you are not limited to a number of rings and can cook with as many pans as you can reasonably fit on it. Hers came with a complete set of pans too, but cost considerably more than my ceramic hob. Unfortunately she could not use her cast iron pans on it as they were not suitable for induction hobs, and she gave them away......
They were exactly the same make as mine, and I could have made good use of them.
