The house is a clapboard two story house and the job was to power wash, scrape and prepare, prime, and apply two coats of Edwards paint. How long on average should it be before the house needs painting again?

We are painting the walls tan with white trim. Should the interior doors be painted white to match the trim or should I just stain the doors? I don’t know which would look best to either match the trim or show the wood with stain?
