Should I install hardwood flooring under my kitchen cabinets?
In your situation, using real 3/4" hardwood flooring should be a lifetime floor. I cannot see any reason to remove it as any other type of flooring in the future could be installed right over it.  Since it is much more likely to have some type of cabinet upgrade rather than actually needing to remove the hardwood, I would install the hardwood wall to wall and install cabinets over it. The actual extra amount of hardwood used under the cabinet area is minimal, and will make installation easier and faster than working around the cabinet footprint.
