Authority Site, Static Page or Latest Post?

I want to build an amazon affiliate authority website, so am thinking about what to use as the homepage, I have the pillar posts that I planned to use for the category pages that will link to each product reviews, but the sites is just based on two niches for now, but I will extend later, should I just use the pillar post as the homepage or what do I?

Please help me as am new to authority site, I have been building niche sites for some years now and I always use pillar post on homepage, I buy my links to the homepage so with the internal linking I the juice gets to the actual inner pages that I want, but for authority site, I don't know how to go..

Response please.
