Sometimes the builders are also the carpenters. I would go with one of those because they will do arguably the most important part right, and they will likely have worked with the foundation team before. Electricians and plumbers often have to be certified so there is less concern there.

Getting educated so you can ask questions and observe that they properly seal the house for air and moisture is a good idea. PGH is a good resource and so is Matt Risingers channel (Build Show).

Consider tapping networks. If you find an architect you like they may know a good builder and vice versa.
