I have found all of this out the hard way:
Besides what in in your stock tool kit and whatever multitool you carry, always carry a 22 and 27 mm socket with you for wheel removal. Everyone has a 1/2" drive wrench of some sort; very few people have sockets this size.
A baby air compressor is worth its weight in gold when you need it.
Ditto for a tire plug kit, small jumper cables and a flashlight.
