categories - So how to redirect category to a page of the same name if it exists?

So I had previously tested a specific redirect where I knew the page exists.

function nepal_template_redirect() {
    if ( is_category( 'nepal' ) ) {
        $url = site_url( '/nepal' );
        wp_safe_redirect( $url, 301 );
        exit();
    } } add_action( 'template_redirect', 'nepal_template_redirect' );

However what I really want to do is include a generic function that redirects any category where a page name exists of the same name. So I thought along these lines.

function pagefromcat_template_redirect()
{
    $category_id = get_cat_ID( 'Category Name' );
    if (page_exists($category_id))
    {
        $url = site_url( '/' . $category_id);
        wp_safe_redirect( $url, 301 );
    }

}

add_action( 'template_redirect', 'pagefromcat_template_redirect' );

However there does not seem to be a codex item for anything like page_exists()

So how would I write a function to do this? Or is there an existing one that I have missed. Thanks

get_page_by_path does something similar:

function pagefromcat_template_redirect()
{
    if ( ! is_category() ) {
        return;
    }
    $category = get_queried_object();
    $page = get_page_by_path( $category->slug );
    if ( $page instanceof WP_Post )
    {
        $url = get_permalink( $page );
        wp_safe_redirect( $url, 301 );
    }

}

add_action( 'template_redirect', 'pagefromcat_template_redirect' );

Seems like I have it now. Largely due to @Michael - it requires of course that a category is exactly the same as a Page Title, but that is exactly what I want.

function pagefromcat_template_redirect() { if ( ! is_category() ) { return; }

$category = get_queried_object();
// $page = get_page_by_path( $category->slug );  -- doesnt work
// $page = get_page_by_path( 'destinations/' . $category->slug); works but with deeper nested locations this will cause a problem, and we will have to have multiple prefixed locations
// atcivities immediately for instance.
$page = get_page_by_title($category->name);

if ( $page instanceof WP_Post )
{
    $url = get_permalink( $page );
    wp_safe_redirect( $url, 301 );
}

}
