Yes – the odd has/had surface mold probably had already started before you even bought it. Since you trimmed it off – you’re good to go.
Unless the sub-primal had been blade tenderized then the internal is not contaminated. As long as your refrig was in proper working order and the recommended temperature range maintained there is little chance for it to spoil.
Otherwise as you have already said the nose is to be trusted for that earthy, nut smell which aged meat has.
Now – enjoy your meat!
