It's not quite as fast but the Thinkpad X13s Snapdragon? Fanless, lighter than the 13" MBA, battery life seems good from reviews, offers M.2 storage and 5G if you need it. There is also an ARM version of the Surface Pro 9 which offers an iPad Pro like form factor but without the restrictions. Admittedly the current ARM PC offerings aren't as fast but they aren't terrible either.
