Canon 650d Focusing Point and Photometric Point

There is no necessary connection between focusing and photometry.

Photometry is nothing more than spot metering. Key metering and evaluation metering are fixed areas and cannot be changed.

As long as the metering mode conforms to the shooting scene, such as taking a face, taking a landscape and evaluating metering, better photos can be taken. Focusing has nothing to do with focusing, but what is clear in a photo.

If you are a novice, it is recommended to use evaluation photometry, and many situations can be handled.
