I need to know the pros and cons of using in wall or in ceiling
speakers vs bookshelves.

Thank you

Flushmounting a loudspeaker solves the diffraction step issue, this can
be an advantage if the loudspeaker is designed without baffle
diffraction step compensation and a disadvantage if it is. Bookshelf
speakers that are actually designed for placing in a bookshelf ought to
be examples of loudspeakers that are suitable for flush mounting. As for
whether an actual loudspeaker is is a different question.

You have almost answered your own question. For each driver there is a
box volume that provides the largest passband with linear response, a
simple infinite baffle and suitability thereof assumed. From this
follows that the reply is "usually not". It can reportedly work very
well, but the driver(s) must be suitable for the specific use.
