The one thing I wish we had was a 'mail' area. I cannot stand having 'non-food' and 'non-eating' items in our new kitchen area. Things like mail, bills ready to be paid, keys, lunchboxes, pens, the newspaper etc. drive me nuts when somebody leaves them on the countertop. If we had a desktop closer to the door, all that 'stuff' would have an official home. From the picture, a full size cabinet would require you to move the plug (which is a PITA if you don't like drywall work). The height of a desktop would be lower than regular cabinet height so you wouldn't have to move it. The buffet idea works too because the height would not have to match your existing counter. If it was a 'floating' top, you'd have room underneath for slippers,a folding stepstool, umbrella stand, or bins to put stuff into.

If you have the ability to mock up some fixtures in your kitchen before choosing, use balloons on string. I learned that tip here. Inflate balloons to the diameter of the fixtures you're considering, and then adjust the height, placement, and number. It's such an easy thing to do but totally changed and solidified my pendant choices.

Photos? Measurements (height, depth and length)?

To start I need to see all four walls of the space and why is the furniture not facing the FP. IMO if there is a TV in the space I would remove all the shelving form the left side get a nice low cabinet and mount the TV above the cabinet so the TV and the FP can share the focal point.
