Vonage uses a miniscule amount of bandwidth. Optik TV doesn't effect your overall bandwidth. So it's not part of the equation. Your internal network printer, external HDD does not matter. Only data from your HDD would be if accessing it from the cloud. (It should be networked at home to access without needing the cloud).
50 Mbps should be fine for what you need. Not everyone is streaming movies or accessing content the same way. If you're heavy into gaming, or stream a lot of 4K content (Netflix as and example) from multiple devices at the same time daily. Then highly consider 150/150 if available in your area.
