How to easily select a home cleverer and Lock Screen background separately

If you are using iOS 16 or later, go to Settings > Wallpaper and follow the instructions. When asked:

choose Customise Home Screen to select a different wallpaper for that screen. Alternatively, on your Home Screen, swipe down from the top of the screen to reveal the Lock Screen wallpaper and long-press the centre of the screen to add a new Lock and Home Screen pair. You can use this second technique to select from your pre-saved screens.
