Two iPads and two iPhones. Both phones updated reasonably quickly. One iPad did the same. One iPad has decided not to go beyond the preparing stage. All use same WiFi system so that does not seem to be the problem. Is only recourse to delete update and download again?

Deleting the incomplete update package from your iPad is certainly a good avenue to pursue…
To delete the failed update from your iPad:
Settings > General > iPad Storage
Scroll down the list of Apps until you find the Apple Update, tap, then select Delete Update.
After deleting the update, a forced-restart of the iPad is recommended:
Force restart iPad (models with Face ID or with Touch ID in the top button)
If your iPad doesn’t have the Home button, do the following:
Force restart iPad (models with the Home button)
Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.
After restarting, you can reattempt the update:
Settings > General > Software Update
In some circumstances you may need to use a computer to perform the update. To do so, you will need access to either a Windows PC (with iTunes for Windows installed) or a Mac (with iTunes or Finder - as appropriate for the installed version of MacOS). Ensure that your installed version of iTunes has been updated to the most recent version; the essential device drivers are included.

Update to the latest version of iTunes – Apple Support
Update software on iPhone, iPad or iPod touch in iTunes on PC - Apple Support
Update your iPhone, iPad, or iPod touch with the Finder - Apple Support
If you have a beta profile installed, ensure this has been removed from your iPad - as, otherwise, installation of production software updates may be inhibited. This support page provides the necessary information to remove the beta from your iPad:

You should note that for your iPad to install an available update, its battery must be charged to at least 50% capacity - and/or be connected to its Power Adapter. Similarly, the iPad can only be updated over a standard WiFi connection - or be updated by a PC or Mac using iTunes or Finder - over a USB connection.
