The screen capture that you posted of your Software Update screen shows the words

iOS 15.8.3

iOS is up to date

As of today, iOS 15.8.3 is the latest version of iOS 15, and the latest release of iOS which an iPhone 7 can run.

About iOS 15 Updates - Apple Support

The "iOS is up to date" message does not mean that you have the latest version of iOS, period. The iPhone 7 isn't compatible with iOS 16, 17, or 18 and will never offer updates to them to you. "iOS is up to date" indicates that you are as up to date as possible for your model of phone.

You can update an iPhone 7 to the latest release of iOS 15.

You cannot update an iPhone 7 to iOS 16 or later.

You can update an iPhone 7 to the latest version of iOS 15. See the Apple Support articles already linked to in this thread. You cannot update an iPhone 7 to iOS 16 or higher.

That's not going to happen, an iPhone 7 can't be updated beyond 15.8.3.

Yes I want to update iOS 16

Not if you have an iPhone 7. You can update one of those all the way from iOS 10.0 to the latest release of iOS 15, but no further. iOS 15 is the end of the line for that phone.

Did you read any of the answers that have already been posted?

Update 7

You cannot do this, if you are asking about iOS 16.
