Best of Luck to You!

For your described use, you might be best advised to choose the basic “entry level” iPad - choosing sufficient memory to accomodate at least double the anticipated local storage requirements for any photographs or other media that you wish to keep on the iPad. As descrbed, you’re not going to need the advanced functions of more expensive iPad models - and the “basic” model (principally designed for educational use) is very capable and will be somewhat more robust than the sleeker more expensive alternatives. That said, addition of a good case is always advisable.

Why do I suggest at least double? This is because nearly everyone will underestimate their storage need - and internal storage cannot be added later short of replacing the iPad. Better to buy it and have it - than not buy it and need it!
