I’m often faced with a choice between:
1. Adding a constructor argument that accepts a lambda
2. Making the class abstract and adding an abstract function
Are there any clear advantages of one over the other? Note: the class does not otherwise need to be subclassed.

In the latter case won't you need a concrete derived class?

I'd say that 1 is significantly better, regardless

Classes are typically constructed once, used many times. The first only complicates the construction site. The second however complicates understanding its usage

So perhaps abstract functions only need to be considered when polymorphism is truly required. i.e. not when you only require the instantiator to fill in some functionality.
