Is it obligatory to make up the missed prayers immediately upon waking, or is it permissible to choose another time for making them up as long as the person has no other preoccupying commitments?

Most Maliki scholars hold that making up missed prayers is obligatory immediately, and it is not permissible to delay them except for a legitimate excuse. Ibn Rushd states that the time for making up forgotten prayers is not restricted, but rather one is commanded to hasten them out of fear of death. He also says that it is permissible to delay them for a certain period with the strong presumption of performing them. Mayyara narrated from Ibn al-Arabi that the repentance of one who neglected their prayers is by making them up day and night, prioritizing them over superfluous worldly matters and news, and nothing should be prioritized over them except for the necessities of livelihood. Therefore, it is obligatory to hasten to make up missed prayers as soon as possible without delay, when one is able. Your prayer is valid, but you incur sin if you delay.
