For the suttas themselves, you can begin with the short ones, so DN which is some copies of suttas form SN and AN, MN, dhammapada, sutta nipata, then SN and AN
Also do not forget the parallel suttas. Scholars already know about this since the 80s, like lamotte says in HISTORY OF INDIAN BUDDHISM (Peeters Press, 1988, page 156):
However, with the exception of the Mahayanist interpolations in the Ekottara [the Chinese equivalent to the Pali Canon's Anguttara],
which are easily discernable, the variations in question affect hardly
anything save the method of expression or arrangement of the subjects.
The doctrinal basis common to the agamas [preserved in Chinese and
partially Sanskrit and Tibetan] is remarkably uniform. Preserved and
transmitted by the schools, the sutras [discourses] do not however
constitute scholastic documents, but are the common heritage of all
the sects.
