Page without menus, title

Hello,

I would like to apply specific attributes to a landing page (which removes menus and title).

For now I use a page ID number hosted in Custom css in a child theme.
.page-id-10679 .site-header,
.page-id-10679 .entry-header {
display: none;
}

How to create a specific “page template” which removes header menus and title ?

Secondly, I am using Suffice theme which comes with a “Page Builder” page template. What added feature does this “page template” provides ?

Thanks.
