class SendVerificationEmail extends Notification {}
class SendAnnouncementFCM extends Notification {}
class SendOtpSMS extends Notification {}

What's the point of those three classes? Why wouldn't you just use Notification directly?

In the given example they don't make much sense but I assume they've done that in case they want them to be extended with new behaviour for certain ones separate from their strategy pattern section in the future

Yeah I assume the same, but I'd really like to see a concrete example of that being done instead of having to guess (as someone who has never used the Strategy Design Pattern).
