Such noises are very difficult for any ANC software, as the ANC software is usually very good at suppressing monotonous, regular noises (such as train noise, etc.), but has more difficulty suppressing noises in the frequency range of the human voice. To put it simply, active noise cancellation works by cancelling out the noise coming from outside with "counter frequencies" so that it can no longer be perceived. The problem with the frequencies you want to suppress is that you still want to understand the person you are talking to, e.g. during a video call. If all frequencies in the range of the human voice were cancelled, you would no longer be able to hear the children screaming, but you would have difficulties understanding the other person and the sound quality would be very poor. This "problem" exists with all ANC headphones, although there are clear differences in quality between the various models.

I find the ANC of the Jabra to be very good, but in my opinion the noise cancellation does not come close to closed headphones, such as those from Bose, because the speakers are on the ear and do not surround it. For ANC, it is always better if the outside noise is already shielded as much as possible by the design of the headphones. However, you should not expect miracles from high-end ANC headphones with a closed design. Even with my Bose headphones, children's noises and screams come through (quietly) despite the excellent ANC and closed design. The advantage of the Jabra headphones for me is that the battery life is many times longer, the microphone has been optimised for use even in noisy environments and the headphones can also be used while charging (which is not possible with Bose, for example). That's why it's my headphone of choice for work. I use the Bose when travelling or at home for listening to music, etc.
