MCU guidebooks include the tie-in materials that are either red-stamped/infinite comics/ or their predecessors(like Public Identity, before the actual invention of the red stamp system.) The MCU guidebooks are the work of head writer Mike O'Sulliven, and the covered comics are completely overlapping (so far) with the list that Corona Pilgrim and Marvel Online Support group given about Canon Materials to the MCU besides the motion picture ones.

Deleted scenes are motion pictures, though sometimes lack the CGI, they were for some very good reasons removed from the movies (even if for the lack of screentime). In case of the Hulk, they've created an extended edition which is completely fine, thats canon; or in case of  IRON MAN 2, they 've added a scripted scene in the official comic adaptation( which was later also referenced in its guidebook), but even that version lacked the scene in which Natasha was flirting with Tony at the part and shooting with the gauntlet; or the WSC hearing of Maria Hill were kind of lacking the cohesion with the rest of the movie.
