What are some pros, cons and recommendations for multicables?
I would not recommend these.  I researched them a few years ago when building and opted to just do them all individually.  Coax (Quad shield RG6), cat 5e, cat 3, and speaker wire.  It was actually more cost effective to buy them all in 500-1000' spools individually, than to buy a lot of multicable.  Plus, the interference can be an issue.  You could combine the phone and network use cat 5/6 for the phones, but again, it was more cost effective to buy them separately.
