Looking at the formula $C = \frac{Q}{U}$ does a high capacitance mean that with a low voltage we can bring more charge onto the capacitor? How is total charge on the capacitor linked with voltage?

If the potential difference across the plates of the capacitor $U$ is kept constant then the charge stored on the capacitor $Q$ is proprtional to the capacitance $C$, ie $Q\propto C$.
On the other hand if the capacitance $C$ is constant then the charge stored on the capacitor $Q$ is proportional to the potential difference across the plates $U$, ie $Q\propto U$.
