It is the only way you can do it. Should go to about 7GB on that phone

Whether it stays there depends on what apps you have installed that may not be so good at data management. Eg Games, Beta Software, Socials...

Possibly, but there are no guarantees. I have done this a few times and initially it looks like the system data has been reduced by a third to half, but it can start creeping up again more quickly than you might expect. Then again, it might not.

Worth a try if you have the time, and a current backup.
