Choosing a font, background, and button style from scratch is the biggest reason a page never gets published. A ready-made template removes that decision entirely, pick one close to your business, apply it, and edit the actual content.
What's available
An online-store template built around showcasing products. A creator/influencer template for a link-forward, social-first layout. A business/professional template with a minimal, trustworthy look suited to consultants and agencies. A restaurant/food template built around a menu and direct orders.
The language question
The template itself, colors, fonts, layout, is language-independent. Every actual word on your page, product names, your bio, block labels, is free text you write yourself, in French, German, Italian, Spanish, Dutch, or English, regardless of the English dashboard you manage it from.
Pick the template closest to your business, then make it genuinely yours in whatever language your actual customers read.
