Wire selection for lighting project

I am planning to install 7 recessed lights in my living room. I am planning to have switches at both ends of the room in a 3-way configuration with all of the lights in between. I will be using remodel cans since the room is on the first floor of a 2 story house.

In order to do this I believe I will need to run 4 wires between most of the cans (hot, neutral, 2 travelers). What type of wire should be used for this project? I have not seen any four conductor cable available, only 14-3 or 12-3.

Then you have not looked hard enough. Try an electrical supply house. They make wire with four insulated conductors. it is often called 14-2-2, since it has two white wires (one is striped) and two hot wires.

Better yet, keep it simple and use 14-3 between the switches, and then 14-2 to the lights from the second switch.

It will be much easier for you to bring power to the first switch and then run a 3 conductor +ground cable to the second switch. From the second switch run a 2 conductor + ground cable to the first can. Run 2 wire + ground between the first can and the remaining cans.

In summary, the two traveler wires need to run uninterupted from one switch to the other. Only a neutral wire and a switched hot needs to go to the fixtures.

Thanks for the suggestion. It certainly makes sense to wire it as you've suggested. One other question I have is what type of sheathing is required for a project like this?

I live in Naperville, a suburb of Chicago and all of the electrical for new construction is run in conduit. For other lighting projects I've done I've used armored cabling but I don't know that this is a definite requirement to satisfy electrical code.

For this project all of the cable will be inside the walls and ceiling. Can I use NM, which would be far easier to work with, especially since I'll be pulling two separate cables through most of the entire run?

You likely cannot use NM then,as that is against city code. You probably can use MC cabling.
