I guess identity theft is the most likely risk? but who knows? and humans are pretty bad at calculating such risks. Changing your phone number is a pretty concrete hassle though, and I guess none of them estimated it worth the hassle… It’s just some anecdata to support the parent’s point.

If your threat model is mostly about identity theft, then switching your phone number and going off whatsapp won't help at all; going off facebook might limit it a bit but not really, as data in FB leaks isn't that relevant to identity theft, that's usually done based on leaks of your data from e.g. Experian which you can't prevent. There are a bunch of somewhat reasonable precautions against identity theft (credit freezes, filing taxes early to prevent tax refund fraud, etc), but those don't include switching your phone number and abandoning FB/Whatsapp.

So from looking at that risk it seems quite clear that no, it's not worth the hassle, because the hassle is real but the benefits are not. It may be different for other risks, of course - e.g. if OP was worried about a specific abusive ex stalking one of their family, that would be a very different story.
