Choose the tool from the editing model and the business rules.
Conventional WordPress
A good fit when the site is content-led, editors want a familiar admin, and plugins cover forms, SEO fields and caching. It is the wrong fit when every page becomes a unique layout that nobody can maintain.
Headless WordPress
Useful when editors should stay in WordPress but the public site needs a separate front end. It adds an API and a deployment. Use it when that split solves a real problem, not as a default.
Next.js
A strong fit for server-rendered marketing sites and product interfaces that share components, routing and an API. Your team will need a content source, which can be this CMS, WordPress, or a custom admin.
Laravel
A practical choice when the website is really a business system: accounts, queues, permissions and server-side rules, with the public pages alongside.
A template theme is reasonable for a simple brochure if you accept its limits. A custom build is reasonable when the content model, the integrations or the performance budget will not fit a theme.
