In my many years of having bikes with internal gear hubs, some new and some decades old, I've never had a single with them.
The internal gear hubs have been perfected before derailers even became a thing; it's a very mature tech.
You can[1] do some maintenance on them. I don't have any experience with that, as all my internally-hubbed bikes were stolen long before such a point :-) :-(
My understanding is that you can't maintain the hub shifter at all. It's sealed so it's generally pretty low maintenance, but if/when it eventually breaks you have to send it to the factory for repair.
