Is the saying of the Prophet, peace and blessings be upon him, "The best of my Ummah are in Madinah," authentic?

The wording, "The best of generations is my generation, then those who follow them, then those who follow them, then lying will spread," has not been reported from the Prophet, may Allah bless him and grant him peace. However, it is authentically reported from him that he said: "The best of my Ummah is my generation, then those who follow them, then those who follow them." After them, he mentioned people who will bear witness without being asked to, betray trusts, make vows but not fulfill them, and obesity will become widespread among them. It is also authentically reported from him regarding Medina: "Medina is better for them if only they knew. No one will abandon it out of dislike for it except that Allah will replace him with someone better than him. And no one will endure its hardships and difficulties except that I will be an intercessor or a witness for him on the Day of Resurrection."
