Would porch paint be a more durable solution to painting cabinets?

I would never recommend using any exterior paint for interior paint unless the manufacturer gives a firm statement that doing so is not a health hazard. The additives used in exterior paints don't lend themselves to interior use. They have UV inhibitors and mildecides and a few other chemicals to slow fading and such and these can off gas for a long time making them very bad for interior use. They make interior paint and exterior paint for a reason... and they make coatings specific to cabinets. Read the label.

Paint cabinets

Make sure they are clean and dry. Remove the doors and hardware. Mark the doors and cabinets with tape where they go. Lightly sand the doors and cabinets to remove any gloss and roughen the surface for paint with 220 grit sandpaper or a green Scotch Brite pad.. Use a tack cloth or damp rag to remove dust after sanding. Prime with a stain blocking primer like Zinsser 123, KILZ,or BIN and have it tinted to the color of the top coat. This will prevent dark or stained surfaces from showing through the top coat. Acrylic, or water base paints are low-fume and clean up easily with water. Alkyd, or oil-base, paints require good ventilation because the paint contains solvents that can irritate your lungs and make you feel sick. Alkyd options require mineral spirits for cleanup, but they provide a hard, durable paint finish. Whichever you use, buy the best-quality paint you can afford for a lasting kitchen cabinet finish. Seal with at least three coats with a water based polyurethane. Use a small foam roller and foam brush for a smooth finish.

I used milk paint on my kitchen cabinets, and more than a year later so far, they have held up perfectly: http://momhomeguide.com/my-painted-kitchen-cabinets-a-year-later/

No just get paint for cabinets you will be fine

I did extensive research on cabinet paints for durability and Mfg type finish. The best paint is latex enamel gloss paint. Be sure to prime first and then use two coats of paint.

I would use milk paint. I painted my cabinets and it was fairly easy. This is my tutorial: http://momhomeguide.com/my-painted-kitchen-cabinets-a-year-later/
