Some questions about SEO for my new website

I recently launched my company's website and want people to find my business online. I've set up meta tags for each page and made the website multilingual. However, Google Search Console isn't indexing the pages in other languages for some reason. My pages still haven't been indexed, even after using the Indexing API. I also created a Google Business profile (not sure if that helps). How can I improve my SEO and get my website to rank higher on search results? I'd like to see my site appear at the top when searching for relevant keywords. I'm considering adding a news section and posting frequently on my website. My niche is freight forwarding services.
