Can you show me a photo so I can see what your looking at?

Of the 2 options, I like the 2nd one you posted. But I agree you can go bigger. How about these: 1. https://www.westelm.com/products/sculptural-metal-pendant-large-metal-shade-brass-canopy-w3396/?pkey=cpendants&isx=0.0.4460 2. https://www.hvlgroup.com/Product/H181701L-PB 3. https://www.hvlgroup.com/Product/H180701L-PB 4. https://www.shadesoflight.com/products/modern-metal-shade-pendant?color=Warm+Brass&via=57e1330169702d78ae0000a5%2C57e133ea69702d78ae0002d1

It is not just the pendants that need changing that linear fixture needs to be replaced, you need to add a ton of storage somehow IMO those pendants are too large for the space and as for bulbs LEDs in 4000K to mimic bright sunlight are always the best in a kitchen the pot lights you will have to replace that lnear light should also be the same LEDs Then when you choose colors you will have them be true. You do know replacing doors is almost the same price as getting new cabinets that would go to the ceiling and all drawers for base that is what you need to do to really get your dream kitchen and BTW yes you are going backwards

IMO forget any light fixture in a kitchen that uses Edison bulbs. All lighting in a kitchen should provide good lighting so look for something in an LED fixture with 4000K bulbs I have no idea of the size of the island but usually 3 pendants ate the norm and If all you want is a linear one it will need to have either the electrical at one end or you need a new electrical box in the center of the 2 old ones. Maybe look at a track type light where the electrical can be anywhere and then choose the pendants you like to hang from it at the proper spacing
