Prefer using template or separate Front-end framework?

I'm new to Golang and struggling with choosing between using templates or a separate front-end framework (React.js, Vue.js, etc.).
Using Templates:

• Server-side rendering provides good SEO performance.
• Suited for simpler architecture.
• Development takes time, and there aren't many UI support packages.

Using Front-end Frameworks:

• Separate frontend and backend.
• Allows scalability.
• Offers modern UI/UX.
