When Mahāyāna Buddhism began emerging (around the 1st century BCE to 1st century CE), it did not completely throw away early Buddhism. Instead, it built on top of it.
Teachings like the Noble Eightfold Path and the Five Spiritual Faculties (Faith, Energy, Mindfulness, Concentration, and Wisdom) are considered the universal, non-negotiable foundations of all Buddhism. A text cannot be recognized as "Buddhist" if it completely rejects these core formulas. Therefore, the Amitābha Sūtra includes them to show that the Pure Land path is a legitimate way to achieve the exact same enlightenment the historical Buddha taught. The Pāli Canon was essentially "closed" or stabilized as a distinct collection by the Theravāda school in Sri Lanka during the 1st century BCE (at the Fourth Buddhist Council).
Because the Amitābha Sūtra was composed later in Northern India and written in Sanskrit rather than Pāli, it was physically and historically impossible for it to be included in the Pāli Canon. The Theravāda lineage rejected it as an uncanonical, external development, while the Mahāyāna schools embraced it as a deeper, "expedient" teaching (Upāya) spoken by the Buddha to a select audience.
In short, the Amitābha Sūtra quotes the Pāli Canon's core curriculum to prove its Buddhist orthodoxy, but its cosmic scope, reliance on Amitāhba, and separate historical origin keep it strictly in the Mahāyāna tradition.
