Getting married on 11th September 2022 (uk)

You have whatever date you wish. The world cannot stop every year over what happened so far back. Also, do you remember 7th July a few years ago in the uk. I bet nobody bats an eyelid over that date when booking.

Think of all the people who had been married on that day before 2001. And all the people who have been born since. Are they never to celebrate their birthdays or anniversaries because they land on the anniversary of a day many people died?

Besides, why should terrorists get to dictate that we can't celebrate anything happy on that day? Letting them control what we can or can't do on that anniversary would be like we're letting them win.

Unless you have someone close to you who was personally affected, and who might struggle to attend a wedding on the anniversary of their loved one's death, I'd go for it.
