How can I build a modern product website like Garmin.com (structure + tech stack)?

Hi everyone,
I want to create a new website with a similar experience to Garmin.com: clean product categories, product detail pages, reviews, compare features, strong performance, and mobile-first design.

What tech stack and architecture would you recommend for this kind of site?

  • CMS vs custom (WordPress/WooCommerce, Shopify, headless, Next.js, etc.)

  • Best way to structure categories, filters, and product comparisons

  • Performance tips (Core Web Vitals, caching, image optimization, CDN)

  • SEO essentials (schema, internal linking, clean URLs)

  • Any “must-have” tools/plugins/services you suggest
