Blog Home Template Confusing

I decided to make a website using Frost and I thought it was really cool, the patterns are beautiful, I changed colors, and I started creating the pages and preparing to build the website for a client. Everything was going well until I decided to create a static home page.
I’m going crazy to understand the logic of the “Blog Home” template. In the site settings, I assigned posts to a “Blog” page and “Home” to a static home page. However, I don’t know what this will be in practice.
The Blog Home template is filled with what would be a static Home page, however, it appears on the “Blog” page, and therefore it does not display the posts while the Home page remains empty, so the posts do not appear in no page.
I’m finding this super confusing. I don’t know if I should have followed any procedure, as I actually didn’t find any guidance for that. The information that appears in the Blog Home template (that has the home page template inside it) says that if a static page is assigned to a home page, the posts will automatically appear on the blog page, which would be normal. However, the opposite of this is happening. I’ve already wasted precious hours of my time struggling with this issue without resolving it.
I don’t have more time, and that’s a shame because I’d like to finish this site with Frost because I’ve already spent time, energy, and study. Excuse my ignorance, however, I’ve created dozens of websites in recent years and I’ve never experienced this bizarre situation. Please ask if someone can help me resolve this quickly, otherwise I will need to rush back to Generatepress or Blocky to finish this site, with rework, and already late to deliver.
I am waiting for an urgent response from a good soul who could bring me some lux and information to prevent me from wasting the time I dedicated to this project with Frost. Another thing that I found difficult was to configure and customize the submenus in the header. The submenus are narrow and I haven’t found a way to widen them, so the submenus occupy 2 lines each when they could occupy just one. Also no hover effect, but I should check that.
These are basic questions. Editing the menu in FSE has been a bit of an arduous task. Am I doing wrong, or what I didn’t understand but could have paid more attention to? Please help me with some light in this darkness that I am now. Thanks to someone who could help me. Thank you in advance. Greetings from Brazil to everyone!
