Can I use a wired connection to transfer data etc to new iPad?

These support pages should get you started with setup of your new iPad - and the methods of transferring your data from old to new iPad:

Set up your iPhone, iPad or iPod touch – Apple Support

Transfer data from your previous iOS device to your new iPhone, iPad, or iPod touch - Apple Support

Use Quick Start to transfer data to a new iPhone, iPad or iPod touch – Apple Support

If the donor iPad, from which you are transferring your data precedes iOS12.4, QuickStart will not be available.

“Transfer” is rather a misnomer. In reality, your data and setup is merely cloned to the new device. Nothing is moved or removed from the original device.

An alternative is to restore either an iCloud or iTunes backup to the new device:

When you are ready, the best procedure for preparing you old device for disposal or reuse can be found here:

There is one method that will allow you to use a wired connection to transfer data to your new iPad. This method requires a backup file, of your old iPad, to be created on a computer (Mac or PC) and then restoring the new iPad from that backup file. The new iPad would be connected to the computer with a cable during the restore process.

All of the other options involve wireless transfers.

Apple also introduced a method to transfer data from old to new device using a direct wired connection between devices with iOS 12.4 - removing the need for WiFi. Documentation for this method is now hard to find - and the feature may have been deprecated in more recent versions of iOS/iPadOS.
