MCC has nothing to do with aircraft (or sim) type and everything to do with CRM. It is quite irrelevant what sort of device you use to provide the cockpit environment. No employer will give you any greater credit for doing the course on a full-motion Cat D A320 than they will on a basic cockpit procedures trainer. As long as the course and the qualification are accredited, that's all they need to know.
Don't waste your money on posh sims - until you need to for type training, should you decide to go that way.
