Painting all the wood trim white throughout the house will update the feel of the space and give a fresh look to the interior. The cabinets look like they are of good quality. I would stain them a medium brown tone. Where you have stacked cabinet doors (one door above another), I would try to have new one-piece doors made to cover the entire opening for a cleaner look. You might want to have glass fronts put on a few cabinets to add some interest. You could also update the cabinet hardware with nickel handles. It looks like you have Saltillo floor tiles. I would have them cleaned and waxed. Replacing them would cost a fortune and they are consistent with the style of your home. Remove the lighting fixture in the kitchen and replace it with something more attractive. If you are going to go with a Mediterranean look, there are wrought iron pot racks which hang from the ceiling; some of them incorporate lighting. I would consider replacing the backsplash, perhaps with glass tiles in the palest green you can find in the granite countertops. Try to do one thing at a time. Start with what bothers you the most. As you make improvements, you may be happier with things that you now see as problems. It appears that your new home has quality finishes. Try to work with what you have and see how it goes. Lots of luck in your new home!
