You seem to be making it more complicated than need be.
Then why does it take so long for the shadows on the ground from objects to move?
At my location the Sun rises in the East at 7:14am and sets in the West 10 hours 59 minuts later. Those complicated shadows move at exactly the same speed.

I think there may be an error in your statement. I copied this excerpt from:
https://www.universetoday.com/26623/how-fast-does-the-earth-rotate/But how fast does the Earth rotate?
You might be surprised to know that a spot on the surface of the Earth is moving at 1675 km/h or 465 meters/second. That’s 1,040 miles/hour. Just think, for every second, you’re moving almost half a kilometer through space, and you don’t even feel it.
This is the rotational value at the Equator and as you travel either northward or southward the speed decreases.

Shadows on the ground at my place take MINUTES to move along the ground or on building walls.
Simply an observation.
Go out and watch one, the shadow does not
zoom along.......
Is 1/1000 second or faster really needed for them?

For the 2017 total solar eclipse, I starting practicing months before the event. I made my own solar filters out of solar filter film from Thousand Oaks Optical and cardboard. I tested the solar filters on various cameras I had back then and found acceptable aperture, ISO and shutter speeds to use before and after totality. You need to take off these filters to photograph totality, otherwise it will be too dark.
I tested my setup the morning of the 2017 eclipse. It worked well. Pretty much normal lunar/solar imaging.

Just in case your 'Search' function is not working properly, here is a post I made 9 years ago that should help out.

If you are serious about getting this right then some planning is necessary.

I'd just use a tripod, lens for the desired field of view, meter on the sun, maybe bracket. Just like any other subject.
Why turn it into rocket science?
Tripod, ok, proper lens, yep. bracket for sure, meter on the sun, WHAT! I almost choked on my coffee with that one. I hope to see your results posted in April.

Maybe, if I shoot it.
Most celestial occurrences happen when it's cloudy here.
Not getting worked up.

Currently via Search reviewing responses to questions regarding the forthcoming eclipse in preparation for speaking engagements.
No one has ever mentioned...wait for it...you can practice before the event. Gimbal vs. ball head? Degree angles? Which lens? which filter? How many stops? Camera settings? Speed bracketing? And get this...you can do it from your own backyard.
If you have little to no experience, call B&H. They can help you without breaking the bank.
Must use solar filter! To protect eyes and sensor.
It is amazing how small sun is, use biggest tele you have, sturdy tripod to prevent camera shake.
Last partial eclipse used mirrorless with swing out screen ( Nikon ZFc) adjusting exposure with +/- dial
In complete eclipse it will get pretty dark, may need to remove solar filter to see corona
Saw a 98-99% eclipse, street lights came on, dogs went crazy
Have handy solar eclipse glasses ( mine carboard and film) in case you want to peep directly.
Squinting does not protect retina

I did exactly that, post extensively as to how I practiced for the annular eclipse which occurred this past October, which I will repeat before the April total eclipse. If you missed my posts, they can be found in the topic I started,
'Preparing to photograph the upcoming October 2023 and April 2024 solar eclipses...', which can be found at:
https://www.uglyhedgehog.com/t-785225-2.htmlJust scroll down to my posts starting on September 25th for a review of what i did and what I learned. Over the next week or so I posted several times with more details as to how my tests turned out, culminating in my images taken on October 14th, the day of annular eclipse.
