As karatestomp states, there are far more interesting texts out there. The Story of Sinuhe says more about the milieu it was written in than most monumental or funerary inscriptions.

Almost all of that "genre" is of the "seen one, seem them all" variety. Most of it's very formulaic—think nicene creed or traditional church hymns, but less interesting. There were a bunch of standard texts that were reproduced on many tombs, and as time went on this body of necessary texts grew, so that's very likely what a lot of this is. Sometimes you'd get some passages of history but those are usually about as dry as the tombs themselves. More often those are on monuments, not buried in tombs, anyway.
"Mirrors for princes" (instruction texts for rulers, often both moral and practical in nature), scribal training texts (yes, really), and their few actual stories that survive, are all way more interesting than the stuff inscribed in tombs, in general. A lot of those don't survive in hieroglyphs, though, but in hieratic or demotic script.
