Is reciting the Qur’an in the mosque more rewarding than reciting it elsewhere, and is it better to recite the Qur’an or make supplication between the Adhan and the Iqamah?

Reciting the Quran in the mosque earns more reward than in other places due to its special status. The supplication (du'a) between the adhan and iqamah is hoped to be accepted, and it takes precedence over reciting the Quran at this time. This is because the rule states that a lesser act performed in its designated place and time takes precedence over a superior act. If there is enough time for both, then combining them is preferable.
