What you need, from a regulatory perspective at present, is an MCC. Any MCC, any crappy old device will do.
But MCC isn't about handling skills, and most JOCs include at least a fair chunk of raw manual flying. Since raw manual flying is highly likely for a selection sim check there is clear benefit in doing one.
Most students are woefully under prepared for the fundamental handling differences between light aircraft and transport category jets.
It may also open a door at some employers.
Coming down the road is the APS requirement that will be a merger of the content of typical MCCs and JOCs.
Some providers are preparing for that by merging their MCC and JOC offerings plus adding the expected APS extras. If you find a course described as 'APS ready' or 'APS compliant' or similar then this effectively means "we intend to use this course as a submission for the APS as soon as it is possible to do so".
Due disclosure: I design and deliver MCC & JOC training as my primary activity.
