I do not want my front page sticky post to show up in a category

You will want to instruct the query to ignore sticky posts on category archives.

function no_sticky_cats_wpse_125862($qry) {
  if ($qry->is_main_query() && $qry->is_category()) {
    $qry->set('ignore_sticky_posts',true);
  }
}
add_action('pre_get_posts','no_sticky_cats_wpse_125862');
