How to memorize the Qur'an and language texts, and which takes precedence?

I am a young man with a strong desire to learn the Islamic sciences. Praise be to Allah, I have started memorizing texts such as Ibn Malik's Alfiyyah and other texts. However, I have not memorized the Book of Allah, and I am unable to combine the two. I prioritized memorizing language texts to protect my tongue from grammatical errors in the Book of Allah, as understanding many of the rulings of the Qur'an and the Sunnah of the Messenger of Allah (peace and blessings be upon him) depends on learning grammar and language. Since I am about twenty-seven years old, I fear that if I start memorizing the Qur'an, I will not be able to memorize the other texts due to my advancing age. And success is from Allah?
What I see for this committed brother is to start by memorizing the Qur'an;Because the Qur'an is the reference for all matters: [Al-Nahl:89], and whoever memorizes the Qur'an and recites it, he has ten good deeds for every letter. If he recites it with reflection and understanding of the meaning, his faith increases. The texts he mentioned, such as the Alfiyyah and other texts of knowledge, he should put off for last. So what I advise him is to hasten to memorize the Book of Allah (Mighty and Majestic) before anything else.
