Hello Monkey Mind,
I was taught the exact opposite ...... that the Abhidhamma scriptures are the minutely detailed teachings for absolute beginners. The Abhidhamma needs to be studied deeply and remembered.
After that, and only after that, ought one to be introduced to the Suttas.
The Suttas have the Dhamma deeply embedded in them and need to be unpacked by someone well-versed in the Dhamma in order to be properly understood.
A significant Sutta is like a half page of notes carried by someone who is about to give a two hour lecture .... the half page of notes are only memory prompts and need to be expanded by someone who knows the subject intimately.
The Suttas are not sound bites recorded from a conversation with the Buddha. They were specially put in this form, deeply packed with significant teachings, so that they could be memorised by the Bhanakas and regularly chanted together - so that alterations and errors would not go unnoticed, and would be corrected.
