Hi @hube2,
currently, I’ve split up the code into setting the available choices for the checkboxes in acf/prepare_field and defining the default value for the field in acf/load_field. I hope my code below is enough to understand what I’m doing.

function wptd_acf_load_brot_verfuegbarkeit_values( $field ) {

    if (!is_admin()) {
        // Only in frontend
        $verfuegbarkeiten = get_query_var('verfuegbarkeiten') ?? $_SESSION['verfuegbarkeiten'] ;
        $sortiment_heute = get_query_var('sortiment_heute') ?? $_SESSION['sortiment_heute'];

        if (!empty($sortiment_heute)) {
            $field['default_value'] = wptd_get_brote_available($sortiment_heute, $verfuegbarkeiten);
        }
    }

    return $field;
}
add_filter('acf/load_field/key=field_5eddd053baf5a', 'wptd_acf_load_brot_verfuegbarkeit_values');

function wptd_acf_load_brot_verfuegbarkeit_choices( $field ) {

    if (!is_admin()) {
        // Only in frontend
        $sortiment_heute = get_query_var('sortiment_heute');

        if (!empty($sortiment_heute)) {
            $field['choices'] = array_reduce($sortiment_heute, function($result, $item) {
                $result[$item] = get_the_title($item);
                return $result;
            }, []);
        }
    }

    return $field;
}
add_filter('acf/prepare_field/key=field_5eddd053baf5a', 'wptd_acf_load_brot_verfuegbarkeit_choices');
