Will the iPad Air 4 case fit my iPad Pro 2018 11 inch?

I was thinking of buying the Logitech folio touch for my iPad Pro 2018 11 inch. Should I buy the case for the 2020 iPad Pro, which will have a camera cutout that is too large, but still fits, or should I buy the case for the iPad Air 4?

I am not sure if the on/off button is the same shape/size as on my iPad. Will the case fit?

anyone that helps gets a biscuit
