FIOS is a switched technology where Cable internet is shared. FIOS can theoretically support more nodes on a segment with better aggregate bandwidth per user than cable can. Copper can currently carry nearly as much BW as fiber (we have a copper gigE link at work) and most top tier BW vendors are using copper as the last mile for it's ease of termination and lower maintenance costs. Newer technologies like CIsco's multiplexed copper cable equipment can/will supply up to 100X the speed of current fiber technology. Having said that, fiber tech is moving ahead and will probably keep up with copper's offerings.
Bottom line is that either technology is fine. There are pros and cons with each one. As far as a phone, I'd lean towards buying internet access and then hang my own phone off the link, something like Magic Jack.
Newer TVs will/do some with Ethernet ports that allow direct access to mutiplexed programming right from the wire. No more digital boxes required. With that comes direct streaming content from sources like Netflix. It's all here now, if you want to pay for it.
