1) You can use the following code (to set "flat rate" shipping method as default) In cart page:

add_action( 'woocommerce_before_cart', 'set_default_chosen_shipping_method', 5 );
function set_default_chosen_shipping_method(){
    //
    if( count( WC()->session->get('shipping_for_package_0')['rates'] ) > 0 ){
        foreach( WC()->session->get('shipping_for_package_0')['rates'] as $rate_id =>$rate)
            if($rate->method_id == 'flat_rate'){
                $default_rate_id = array( $rate_id );
                break;
            }

        WC()->session->set('chosen_shipping_methods', $default_rate_id );
    }
}

Code goes in function.php file of your active child theme (active theme or in any plugin file).

2) You can also reorder the shipping rates in your shipping zones settings (but it doesn't really works as the last chosen shipping method take the hand).
