The single biggest difference between e-commerce SEO and everything else is scale of accidental URLs. A store with eight filters across four categories can generate more crawlable combinations than it has products, and Google will spend its crawl budget on them unless told not to. Meanwhile the category pages that actually rank get visited once a fortnight.
The second difference is that category pages, not product pages, do most of the ranking work for non-branded queries. Most stores invest heavily in product descriptions and leave category pages as a bare grid with a title. That is the wrong way round for anything above the long tail.
