Thank you for your rapid reply but there is one fortuitous difference in the description:
Note that in step 3 under "If you can't remember........" on "Learn What To Do" it states, " it will reset settings like display brightness, Home screen layout, and wallpaper." as well as the encryption password.
This was the bit I was dreading, resetting my home screen layout. I had to do this once before for a different reason and the Home Screen reverted to an alphabetic list of native apps and all my folders of third party apps were gone. As you can imagine it took a while to recreate the layout as it had been.
But it didn't happen. After Resetting All Settings only my Lock Screen image changed, everything else remained the same on my Home Screen. Of course all my WiFi settings were gone and my Location and Notification settings but resetting them is not a bad thing anyway. It also deletes the device name, returning it to "iPhone".
Maybe this is a change in iOS 14, I cannot say but if it is it's a good one. Returning my iPhone to its original state took almost no time at all. Yes, I did have to set up Apple Pay again but the previous card I used was remembered and I had the option to use the same card again just be adding the 3 digit number on the back.
To sum up, if you must Reset All Settings it's nowhere near as daunting as it used to be.
