I thought though that capturing V-2 launch sites were a top priority
and so diverted offensive attention from other, perhaps more promising
areas of the front? Or did I just read too much into the dialog of
"Patton?-)"

Unlike the V-1, which needed its fixed catapult for launching, the V-2
could be launched from any site within a few hours once it had been
surveyed to determine its exact longitude and latitude - as the whole
launching infrastructure was road-mobile. So the only way to stop
attacks on England by it was to capture all territory that would have
allowed it to get in range of its targets (its range was 234 miles).
The V-1 sites were a target for allied ground forces to grab in France,
but I don't know if the V-2 sites mentioned in the movie were a
confusion with those.
There's info on the mobile V-2 operations he

Quite a few V-1s were also airlaunched from carrier aircraft.

One attempt (Operation Sandy [1]), which was successful. However, the
results of Operation Pushover [2] convinced the Navy that they wanted
no further part in having big liquid fueled rockets shipboard.

I've got a 1/48th scale model of one of those by Revell Monogram.
It's a He-111 H-22, and is a really nice kit.
Accuracy on the air-launched ones was really bad, to the point where the
British couldn't figure out what the intended target city was in some cases.
The V-1s also sometimes exploded while being carried or at launch,
destroying the carrier aircraft.
There's footage of one being launched starting at the 1:45 part of this
video (the first part is the Hs-293 rocket-boosted glide bomb):

As you can see, the V-1 oscillates quite a bit after launch as the gyro
tries to get it on course and stabilized into level flight.

No they did indeed launch a V-2 off of a carrier (the Midway), they did
it only once as it was very unstable on launch, and another test where a
fully-fueled V-2 was purposely exploded on a section of simulated
aircraft deck put them off on the idea of liquid fueled rockets on Navy
ships.

I don't know if having it come off the pad at around a 60 degree angle
would be "succesful".
At least it didn't skid straight into the deck island.

However, the
results of Operation Pushover [2] convinced the Navy that they wanted
no further part in having big liquid fueled rockets shipboard.

Imagine that on a wooden carrier deck, like out of WW II.
Oh, that would have been something to see.

Aren't solids purported to have less "gentle" failure modes than
liquids?

Once ignited they sure can blow up, but the advantage is that they don't
need a LOX plant on the ship if you are using either alcohol or kerosene
as fuel, or going up when their hypergolic propellants leak like on the
K-219 Soviet submarine. Storage of a solid-fueled missile on a ship or
sub is a lot like storing a vastly scaled-up artillery shell as far as
safety goes.
One of the things that "Pushover" test resulted in was getting the idea
of putting Jupiter IRBMs on surface ships canceled, and converting the
sub-based Jupiter concept to a solid-fueled form, which led to the
smaller Polaris once thermonuclear warhead size decreased.

That's for in flight failure modes - in storage, solid fuels have the
overwhelming advantage that they don't leak, outgas, collect ice, eat
their way through the walls of the tank, etc.. etc..
