My 2018 VW Golf does have a limiter as a second mode of the cruise
control system. If I press the cruise control button twice, it will
engage the limiter mode. For both modes, I must set the speed / limit
myself.

Mine does not nag. It simply refuses to accelerate beyond the set
limit. If I need an emergency acceleration, I can override the limiter
by applying full accelerator pedal (kick-down). A gonger will sound,
and I get full power acceleration.

Mine is part of the cruise control system, so it must be manually
enabled if I want to use it.

My car does not have a camera, nor a navigation system, so it does not
know the speed limit. I have to choose the speed myself.

Is it useful? I have used it only once or twice, on a narrow country
road that was a mix of long straights and tight corners. The speed
limit was too fast for the tight corners, so the normal cruise control
mode was too scary. I rarely drive on roads like that, so for me, the
limiter system is of limited value.
