Under 300mm wide: The 2021-2023 HP Aero 13 are popular 16:10 13.3" HP laptops with the navigation column of Home/PageUp/PageDn/End keys, though it has half-height up/down arrow keys. It seems to be about 297 or 298mm wide (11.72"), which is only a couple mm wider than the 296mm of the Framework Laptop 13.
Sadly, HP might be discontinuing this keyboard, as the 2024 model seems to lack those keys in early previews.
