Do you ever use standby on your transponder?

I don't. It stays on 24/7 (you know what I mean). 1200 unless given a
code. It effectively prevents "Maule, check your transponder" unless
using the wrong code.

I make no attempt to turn it off or go to standby while taxiing or
anything else. I've never been asked to go to standby or otherwise
questioned.

This has been discussed before but I'd suggest the everyone can do this
without causing a problem for anyone.

I don't.

I was taught to switch from standby upon starting to roll down the
runway for departure. The reasoning that was cited had to do with
radar clutter on the airport surface.

ADS-B may change this practice, however.

I think that is a myth. I don't think the computer shows ATC your
signal if your altitude shows you at ground level.

It's not a myth. The computer doesn't know where the ground is, it filters
out only whatever it's told to filter out.

You were taught to mess with non-essential stuff on the runway? I once flew
with an VFR pilot - he wanted to see what IMC was like - it was a great
flight (lots of IMC) and he did amazingly well in the clouds - I was
impressed. I let him land - right after we touched down, his hands were
moving around the panel so fast I finally just slapped his hands hands and
said "Stop! Do that when we're stopped on a taxiway."

I'm not sure I'd characterize it as "non-essential."

I was taught the "Lights, Camera, Action" reminder phrase where
'camera' signifies transponder on. This mantra is to be uttered in
the beginning of the takeoff roll.

Lights: strobe, landing lights, etc.
Camera: transponder
Action: mixture, props, throttle, airspeed alive, ...

My suggestion would be strobes, landing light, transponder before taxiing
onto the runway - you do want to be very visible on the runway too. Also
get the mixture and props. The only items when are the runway are throttle
and airspeed alive - also look for other aircraft etc, think about abort
procedures, how your take off roll is progressing (I have a good story on
this one) etc... I don't like to be fiddling with stuff during the takeoff
roll because there is so much other important stuff to do and to think
about, also, when you fly complex aircraft... Well there's this pesky
little lever that also finds its way into the FAA accident reports.

The same goes for landing but in reverse; i.e. don't touch anything until
stopped on a taxiway (or something similar) - basically not on the runway.

Just my opinion.

I agree with Hilton. Checking the transponder is an unnecessary distraction
during a takeoff. You should be watching for other traffic and your engine
gauges. If the transponder is off, you will find out sooner or later. Same
with lights or strobes. But if you miss a low oil pressure reading, or a
conflicting traffic, the outcome may not be so good.

The controller says, "Cherokee 12X cleared for takeoff."

And you reach over and twist the transponder knob, apply takeoff
power, and the "distraction" is gone. It's not a very big deal.

Right. Those are some of the things that should happen, and there's
nothing to prevent them.

If the transponder is off, you will find out sooner or later.

Absolutely.

Same with lights or strobes.

Umm, not necessarily. If it's day VFR/VMC, and you want to burn a
landing/taxi light to enhance conspicuity and discourage bird strikes,
you may not become aware of the fact that the light is off.

But if you miss a low oil pressure reading, or a conflicting traffic,
the outcome may not be so good.

True. But I don't see how twisting the transponder knob before adding
power interferes with those things.
