We are building the home right now and we need to decide on the wiring for our design appointment. Let me see if I can find a picture from model

It depends what they are made of? Glass, Metal or something else? If they are a heavier looking light you definitely should go with something smaller.

Given the size of your island, I don't think 3 pendants would be too many. I've also seen photos of large islands with only two pendants that are beautiful. Think about where the pendants would hang should you choose two or three and stand at the island. Do the pendants obscure your view of a focal point in your room? What about your line of sight into another space? I'm renovating my kitchen and downsizing my island to 5'. I'm considering an 11" pendant and will use two because I am able to place the pendants so that the distance between the pendants and the distance from the edge of the counter to the pendants is almost equal to the size of the pendants. As long as the scale of the pendants feels appropriate to the space, I'm sure whatever you choose will be beautiful because you made your choice based on what makes you happy. So take the advice of your electrician, and me, with a grain of salt and choose joy. Would love to see the end product.

Different goals come into play. Task lighting for when you work at the island counter requires 450+ lumens at the surface. The source should be placed so you don't shadow the work with your body. Ambient lighting is another objective. Recessed led cans on dimmers can do both. Pendants on dimmers or pendants and recessed lights can also do both. In addition, pendants can be decorative. Adequate task lighting is often missing in kitchen design.
