Doesn't a SIM swap attack impact more than just a single user account of a service? They lose access to SMS and calls from their phone. I'd argue they learn that there's a security issue earlier and cause them to take action (contact carrier or authorities).
A friend's Mom's Facebook account was recently hacked. They didn't have 2FA set. Hacker changed her email address in the Meta account. Meta did not notify her via email of the email address change. She did not use fb for a couple of months and had no idea this had happened. Then she began receiving calls from cousins and relatives saying their account was hacked after receiving a link in a message from her.
I would've advised her to use SMS 2FA. A lot of non-technical folks from an older generation don't even bother with email.
