I would avoid finasteride at all costs in my opinion. It kind of defeats the purpose of cycling. If you don't know what it does, then I would suggest doing a little bit of research.
For your cycle, you basically will just want to stay away from DHT compounds.
Really, the only thing you need for a successful cutting cycle is Test and a good diet. Everything else is just icing on the cake because they provide more calorie partitioning and muscle hardness.
A couple of options you could look look at would be Test and NPP, like you stated, or Test and EQ.
