@Douglas-Kryder , I looked though all of the openly available documentation. The only document which addresses low-level stuff like peripherals and general SoC behaviour seems to be the Datasheet.

@luz , I did find that MT7628_ProgrammingGuide, but in a first look it seemed to have pretty much the same content as the datasheet... But thanks for the info, I'll be looking for stuff on both documents now,

What you said about the different market positioning is true. As a product developer the main reason for going with MT7688 (and Omega) has to be the price, which seems to be unbeatable. Unfortunately we can't have everything...
