I am not a fan of “waiting” to an older age (unless still actively working full time), to increase the monthly amount. Just invest the money, if you don’t need it. But if you wait, and you die before collecting, you will end up getting ZERO.
Best to use the Social Security first, before dipping into your other savings or retirement accounts, since you can generally leave the other accounts to your spouse or children.

Good advice.
Once you are dead, you won’t care. I just started drawing at 70, snd am satisfied with my decision
