How to format a page using WordPress the_content hook?

Hi,

I'm using the_content WordPress hook to add additional content to a blog page. The code works for the target. However, as hook intercepts all content, I am having a problem on the WordPress pages where shortcodes are not rendered and other formatting does not occur. Is there something missing in my code?

Here is a link to my code - the_content hook

For everybody to quickly view the code, this is what is in the linked paste bin. It will be easier this way.

function display_comment_summaries() {
    $p = get_post();
    $output = '';

    if ( is_front_page() && is_home() ) {
      // Default homepage
      return;
    } elseif ( is_front_page() ) {
        // static homepage
        goto display_the_page;
    } elseif ( is_home() ) {
      // blog page
      goto display_comments;
    } else {
        //everything else
        goto display_the_page;
    }
    display_the_page:
    $output .= $p->post_content;
    goto display_output;
    
    display_comments:
    $num_comments = 5;
    $output .= $p->post_content;
   if (( $p->comment_count ) > 0) {
       $output .= '<p style="font-weight: 700; margin-top: 10px;">Latest Comments</p>';
       $output .= '<ul style="list-style-type: none; margin-bottom: 10px; padding-left: 0;">';
       $comments = get_comments( array ( 'post_id' => $p->ID ) );
       if (($p->comment_count) < $num_comments) {
           $num_comments = $p->comment_count;
       }
       $i = 0;
      foreach ( $comments as $c ) { 
          if ($i < $num_comments) {
               $day = ltrim( substr( $c->comment_date, 8, 2 ), '0' );
               $year = substr( $c->comment_date, 0, 4 );
              $month_name = date( "F", strtotime( substr( $c->comment_date, 0, 10 ) ) );
               //$output .= '<li>' . $c->comment_content . '</li>';
               $date = $month_name . ' ' . $day . ', ' . $year;
               $output .= '<li>' . $c->comment_author . ' on ' . $date . '</li>';
               $i++;
          }
      }
       $output .= '</ul>';

       $output .= '<p><a href="' . get_permalink( $p->ID ) . '#comments' . '">' 
            . 'Read Comments</a></p>';
   }
   display_output:
    echo $output;
    
}
