I really like the larger screen current gen Ipad Mini that I use with my Mavic Air 2.  Is this not an option if I move to the Mavic 3 family?

you can still use iPad mini, but you will need an RCN1 , its the cheapest option and if you already have one cheaper again.

Great thanks.  

I still use my 12.9" ipad.  The best way to fly in my opinion specially if you're taking pictures.

Hello there AE1M. Thank you for reaching out. I hope that our fellow DJI Co Pilots who uses an iPad when flying there DJI Drone can give out the best information on this matter. For additional reference I will post a DJI Link where in you can find the recommended mobile devices for the DJI Fly application below. Thank you.

The list doesnt included iPad Mini which is what I have been using for my Mavic 2 f since I bought it about a year ago with a nice holder.  Much easier to read than a phone.  I pair it to my iPhone 13 for internet connectivity.
