The differences are so little for that amount I'd just park it in a VG MM for ease given I already have a VG account.
When long term CDs were significantly higher I would consider them if you think there is at least a fair chance you will not be using the money. It varies from bank to bank, but some banks' penalty for pulling out of a long term CD early is not that bad and u ending up making out well anyway (Ally Bank one of them). BUt in this interest rate environment I'm guessing just going with MM is the way to go.
