I wonder if there's some difficulty in getting the shift right on
these 11/12/13 cog cassettes that's making the wireless shifters
popular. Are they more precise?

Don’t believe so no is mechanical 11/12 speed stuff certainly. Is more narrow but no mechanical aka cable can and does work fine to the best of my knowledge.
Wireless does do away with electronic cables and the routing of those.

The motor/electronic controls are significantly more
accurate and repeatable than a cable system. It's not so
much of an issue with ten speed and fewer since you have
more tolerance (aka'slop') in the system, but as the
tolerances grow tighter the simple psychical changes in the
system as it wears would mean more frequent adjustments.
Enough wear in the system can result in mechanical
hysteresis which would make accurate shifting all but
impossible.
Electronic shifting (wired or not) removes the biggest
variable in shifting accuracy and repeatability - cable
wear. Also, electronic systems can use feedback to fine tune
derailleur positioning to compensate for any mechanical wear
in the derailleur and chain.
Theoretically, electronic controls are vastly superior to a
manual control system. However, many people are of the
opinion that it's just something else to go wrong (and for
the most part, inherently unrepairable). They aren't wrong.

Much agreed. Add in complex failure prone cable routing on several
modern design frames (not only rear suspension).
And yes again that removing cable troubles doesn't mean removing control troubles altogether!
IMHO electronic shift advantages are not specific to 11-12-13 systems in
that I have a few customers running those with friction shifters without complaint. But electronic shifting is indeed much more precise and repeatable for any derailleur system.
