Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter
How you run the cables under the tape depends on the bar and personal preference. Some bars have cable grooves front and back and you'd use one for brake and one for gear. Others have a single wider groove in front, and you'd route both there. Or some have no grooves and you route however you prefer (I prefer both housings in front, but that's just me).
As for crossing in front, some folks believe that makes for a gentler more open curve in the housing and lower cable friction. I'm not one of these, but don't debate it. Like how you route cables under the tape, it's a "to each his own" issue.
IMO, there are no rules, except that then housings must be tight to the lever, and you need to be careful not to pull them away as you tape them into the curves.
