A CD isn’t the only option. A 2-year treasury note pays 4.82% right now. You could do that and then reevaluate in 2 years. Having more accessible/liquid assets leads to more flexibility if you need money for an emergency or even a move or downpayment or whatever.
There’s also the very remote possibility for loan forgiveness.
I don’t think the interest spread is large enough for that to be the “slam dunk” answer though. If you’re not great with money or just don’t want to deal with another administrative burden I’d lean towards just being done with the loans.
