Reduced/Oxidized based on Ecell

I learned that the more positive Ecell refers to the reaction being reduced. If the given Ecell for two reactions have the same value, which will be considered oxidized/reduced?

Maybe you can look at the oxidation numbers.

is one of the E cell values under standard conditions?

Yes, if there is a difference in concentrations or other factors, then this will contribute to which species is oxidized/reduced.

If the Ecell is the same, the substance that is oxidized/reduced will depend on the concentration. The substance in lower concentration will be oxidized, while the substance present in higher concentration will usually be reduced.

One with lower concentration will be oxidized

Since the Ecell values are given under standard conditions, you would also have to take into account other factors such as the concentrations of the cathode and anode, as well as the temperature. The anode (oxidation reaction) will occur at the lower concentration of substrates, while the cathode (reduction reaction) will occur at the higher concentration of substrates.
