Sorry if this has already been stated but if you’re looking to start fresh a factory reset will suffice. From a digital forensics perspective I’m not familiar with a way to fully 0 out the device. There may be a tool that will overwrite every bit on the disk but I don’t know of one.

I googled for DFU(restore), but still don't know what it is and how to DFU restore my iPhone.

Did you restore the phone as new without loading any backups or even getting iCloud data from an existing account?
What should I do with my iCloud settings before restoring my iPhone?

Hardware. Memory and storage along with battery and how well it regulates each along with temperature. It's 5 years old. A newer refurbished model that can run iOS 13 is in your best interest.
Agreed. Even the 6s is a night and day upgrade from the 6. The A9 with 2 GB of RAM is holding on strong with iOS 13.

So what do I do after entering the DFU Mode?

Besides, what should I do with my iCloud settings before restoring my iPhone?
