If you are not going to do any adjustments, it doesn't really matter which you bottle, first.
I bulk age, also. IMO, after a year in the carboy, there is not much advantage in not bottling the wine. Especially since you are not aging in a barrel. (I also assume you don't have any oak currently in the carboys.)
Also, if you don't have a very stable temperature, as atmospheric conditions change, a certain amount of "breathing" is done by a carboy.
This breathing allows some oxygen to be drawn into the carboy. This
affects the SO2 levels inside. Be sure to check these levels and add any needed kmeta every 3 months or so.
I recently read a professional wine maker's report that tests show leaving a wine under air lock for extended periods of time (passed a year for sure) can allow much of the wine's nose, aroma to escape. So, which ever one you leave in the carboy, I'd use a solid bung.
Some wineries leave their wine in the bottle for a full year or more before distributing it.
So:
My first choice would be to bottle both of them.
Second would be to bottle the Pinot to protect its delicacy. Place a solid bung in the Cab carboy and test every three months.
