Apple MacBook Pro, Air, or iPad?

[Mountaineer]

I will soon be in the market to update from a purchased new 2018 Apple MacBook Pro with a 15" screen. I do not like the keyboard in the 2018 nearly as much as the keyboard in my previous 2009 MacBook Pro. My "getting older" eyes prefer a larger screen but in something relatively portable. I am not a power user; email, relatively non-super-complex spreadsheets made with Apple Numbers, some writing using Pages and many of the other Apple apps that come standard like Photos, FaceTime, Notes, Calendar, Reminders. I definitely do not want anything with Microsoft or Google operating systems; I have other Apple products that I plan to keep using (HomePod, iPhones, Apple TV and perhaps an Apple Watch in the future).

I would appreciate your thoughts re. my getting a latest model of MacBook Pro, MacBook Air, or iPad with a keyboard, all with the largest screen size available, or anything else you might suggest I consider. Thanks for any and all comments.
