You need to meet your clients needs when it comes to data cabling. Wireless is not standardized yet and and IP [internet protocol] based products are soon to flood the market. Telephone, video, audio, security, power-over-ethernet devices all run on cat5/6. Lutron home controls can in a pinch use cat5. Crestron home controls thrive on cat5
Home audio systems use cat5, and lots of it.
You need to discuss the options and don't be afraid to call in an AV dealer for info and suggestions.
My basic spec style jobs get a cat5/rg6 to all bedrooms and living spaces, better homes get a bannana peel [2cat5/2rg6] to all plus some bonus areas. The more custom homes can rival high voltage wire in their quantities. It just comes down to what the customer wants.
Your method sounds good as it covers all bases, just make sure it is spelled out to who ever pays you, as a phone only opening could end up costing $300+ And power outlets can get crazy as well. My AV partners run all TV and audio equipment power back to a single source, then run it thru power quailty equipment. A bit overkill but it works for them.
