According to a report from 9to5mac, Apple could be working on full cursor support for the next major version of iOS and iPadOS. The report is based on code of an early version of iOS 14 and iPadOS 14.

If Apple ships that new feature, it means that you’ll be able to use a Bluetooth mouse or trackpad with your iPad to move a cursor around the screen. It would work pretty much like a mouse on a desktop computer.
