Don't over think this.

The CAN specification does not define the physical implementation like wire or connectors. The 2CAN and Jaguars use the common and inexpensive phone cable to make CAN easy to implement for hobbyists.

Your team will not gain anything by reinventing the CAN bus physical interface. The runs are short. Don't worry, use phone line and terminate with either 100 or 120 ohm resistors. Either will do the job.

Don't use a cap to filter anything on this bus. Use caps on motors if you need to, but keep to the recommended cabling for this bus.
