I came to post a thread asking for keyboard layout with full size arrow keys too!
My favourite layout has full height arrow keys, and a column of home, end, page up, page down on the right edge of the keyboard, rather like that dodgy amazon laptop linked. No one uses the right shift key (there’s even memes about it), feel free to tuck a 1x1 shift left or right of the ‘up’ key.
The Lenovo Yoga 700 14’ (which was the last laptop I purchased) is another good example.
Or the Asus EeePC 1000HA had full size arrows, and a small right shift that I remap to page down. Which was fine too.
