Current best practice would depend on what you are trying to do exactly. But overall the fastest way to transfer files to/from iPad (both in terms of ease/speed of use, as well as the actual transfer speeds) is just hooking up an external drive (whether it is a flash drive or an ssd) and transferring files using Files app (aka the file browser app preinstalled on all iOS/iPadOS devices). Note: this relies on the assumption that you have an iPad with USB-C (aka pro models and some recent non-pro models).
