Currently there is no Cut Polygon Tool for Pro and you have to use Split or Divide. The problem with Split or Divide is the attributes are constrained by the domain split policy. The default for this is to NOT duplicate the attributes. So when you use the Split tool you lose of all your attributes as a default. ArcMap users never had to worry about this because the Cut Polygon Tool was mostly used and it keeps your attributes, it is not constrained by the domain split policy. The Split in ArcMap was only for those with Advanced licenses. If you have a lot of databases with domains you now need to go and change the domain split policy for every feature you want to keep the attributes when you split.
