See https://www.advancedcustomfields.com/resources/dynamically-populate-a-select-fields-choices/

function acf_load_categor_field_choices( $field ) {
  $args = array('public' => true);
  $sites = wp_get_sites($args);
  foreach ($sites as $site) {
    switch_to_blog($blog_id);
    $categories = get_categories();
    foreach ($categories as $category) {
      // I'm using both the blog id and the term id for the
      // select value so that you'll know what site to get
      // the category from
      field['choices'][$site['blog_id].'-'.$category->term_id] = $category->term_name;
    } // end foreach category
    restore_current_blog();
  } // end foreach site
  return $field;
}
