Choosing a WordPress theme gets much easier when you start with the business model instead of the visuals.
For service businesses, your theme should support trust-building sections, clear calls to action, and lead-generation flows. For publishers, editorial hierarchy and reading experience matter more. For storefronts, product browsing and conversion speed should drive the decision.
A good niche theme does not just look relevant. It should reduce setup time, match the content structure you actually need, and make the primary action on the page obvious to visitors.
