Looking for opinions on whether to install patch panel or cross connect voice and data devices. These will be large installation/IDF's. Also site will have many moves, adds and changes on going.

Would go with the consultant, cat5 to every outlet and just connect the switch to rj45 patch panels and cross connect.
Have done a site were I have spread the switches ports digital and analogue between the cabinets so all you have to do is move things in software and re patch in required, sipmles.

Wall mount jumper wire systems are the best and easiest to add cables later. You get more for your money $$$$$
Note:
Most contractors install voice and data patch panels, that are actually a number of independent networks, each doing its own thing, over there own set of wires and cables. The problem with this is you have no flexibility of configuration. In other words, you are stuck with what you have, and if your need change and you will most likely have to rewire to accommodate them. Each jack is less powerful because of its specialized use. Total system cost must be much higher for a given level of functionality. The system will work, but is neither structured, nor optimal.
"Cheap Patch Cords"
Most if not all contractors test and certify for a link configuration and not a channel. The contractors link measurements are done with special equipment and patch cords that come with the tester. The network is usually installed weeks before the computers. As a result patch cords are often purchased at the cheapest possible price with no consideration for performance. Don't let cheap patch cords be the weak link, in your IT structured cabling system, whether that system is copper-or-fiber-based.
Cheap patch cords will cause impedance mismatch between components and will result in signal reflections at low frequencies.
