I have ACF PRO version 5.8.7, and I still getting an array instead of a string from acf select fields when this is inside a flexible content. So I used designertastic conditional code to create a function and then used it on every select field.

/**
 *
 * Array to string.
 *
 * This function is a workaround to ACF Select fields that sometimes output an array instead of a string.
 *
 * @param array $array Array value.
 * @return string value as string.
 */
public function arr2str( $array ) {

	if ( empty( $array ) ) {
		return;
	}

	if ( is_array( $array ) ) {
		$string = $array[0];
	} else {
		$string = $array;
	}

	return $string;
}

Usage

$button_style = arr2str( $button['button_style'] );
$button_style = arr2str( get_field( 'button_style' ) );
$button_style = arr2str( get_sub_field( 'button_style' ) );
