I'm thinking about building a blog page using headless CMS, that said, I'm new to headless CMS world and currently is in a researching phase.

1. What aspects should be considered before making a choice (e.g., must-have features, must-avoid due to issues, etc.)?
2. Which solution would you recommend? Why?
   • Strapi
   • Contentful
   • Directus
   • Sanity
   • GraphCMS
   • Prismic
   • Drupal
   • WordPress
   • GhostCMS
   • Or something else

Some requirements on top of my head are (not strictly required though):

• Has Next.js / TypeScript integration (dynamic website)
• Has cloud hosted options
• Has SSO (e.g., front-end users, back-end users, etc.)
• Has markdown editor
• Has article scheduling
• Has localization
• Has content backup to GitHub or third-party storage solution
• Has SEO integration (tags, analytics, schema, etc.)
• Has a wide variety of configurations, such as plugins (mailing list, webhook, payment, etc.)
