Digital BW, The Print

As a general rule, when developing B&W negs for both scanning and 
traditional darkroom which paper grade (i.e. II or III) would it be 
preferable to standardize my film development?  In other words,
should 
I develop my negs for a lower or higher contrast?
Many thanks in advance to all who share their time and experiance in 
answering my question.
Peter.
