I don't think anyone has settled on a multifunctional connector for 3d printing yet. A connector with some low current and some high current options would make sense.
The current per phase is for each set of coils of which there are two per motor so 0.6A per wire pair. If you look at the cables to stepper motors they're fairly insubstantial, standard dupont connectors are up for the job so unless you're thinking of using something smaller than that you should be okay.
Its heaters that pose the challenges when using ethernet cable or serial cable etc... You need to use multiple cores to meet the current rating and apparently this isn't good practice.
