You're absolutely right that you can pass reusable form field markup to add_settings_field(). The trick is to define the data type for each setting, and then pass the same callback to each call to add_settings_field().

function outputFavIcon() {
global $settings; ?>

function journal_check_cats_callback() {
$options = get_option('journal_theme_blog_2_col');
$pag = journal_theme_blog_2_col;
$_cats = get_terms( 'category' );
$html = '';
foreach ($_cats as $term) {
$checked = in_array($term->term_id, $options) ? ...
