Given that Apple seem to like keeping previous generations around now, it might be a good idea to make the numbering an official part of the iPad name - such as it is with the iPhone. It's dumb to see ' this year's iPad' or the 'NEW IPAD' and even 'the 2022 iPad' is a bit clumsy.
Have
iPad mini
Ipad air
iPad Pro
Use air for the mid-range iPad since just 'iPad' isn't enough to clearly distinguish it - people will start sayings like 'the middle iPad' or 'the iPad standard' or the 'iPad normal one'.
And then append the number of generation next to it. eg iPad Pro 10.
