Is a house phone and cable necessary?

Me and my husband just moved into our new house. I ordered Verizon fios but just for wifi and also I chose the option of no annual contract. For the same price I could get house phone and cable but I would have to do a 2 year agreement. We have 2 cells phones each iPhone and galaxy note and we have Amazon Fire sticks where we can watch all the tv shows and movies we want! What's your opinion? Should I call back and change my order and just get the phone and cable with the 2 year agreement or is it not necessary???? Help please?🤔
