Personally for these sorts of things I tend to do only very basic validation in a constructor if it's ever needed, and directly throw an exception there specific to the class the constructor is in. PHP can do all the type checking for you (it's much better in PHP 7.1 and up) and you can wrap calls to constructors in a try/catch block to handle them better and give the user the error output you need them to have, whilst logging more full information.
