Is there any pros/cons for wiring them in series, especially since most 2x12s come with 16 ohm speakers wired parallel?
you probably will not hear any difference in sound at all, is most feel change (a series have a more "saggy" response and the parallell have a more open sound, but again, is barely noticeable.
as for tech side of the things when you wire'em in series if a speaker blow in the middle of the gig you are done, since the sound will not pass through/to the other speaker. in parallell if a speaker blow you can carry on with the good one and finish your gig safely
