As an Earthling, it’s easy to believe that we’re standing still. After all, we don’t feel any movement in our surroundings. But when you look at the sky, you can see evidence that we are moving.

How fast is Earth moving through the universe?
Interesting
but no total speed yet found.

Zero

These two are interesting for the proposed hypothesis of extinction level events and their movement encountering something that gravitationally affects us
How Fast Is Earth Moving?
You will need to specify a frame of reference.
ie: “Relative to something.”
Movement in space is strange as well you could be travelling at many tens/hundreds of thousands of km’s and hour and with no reference point look like you aren’t moving at all

Would galactic centre be a decent reference

Swinging around towards something like a black hole .
Sensitive gravitational detectors will come in handy.

It’s up to the person asking the question to specify a frame of reference. That is one. Another might be the centre of Andromeda. Others might be the moon, or the sun or, anything really.

Are any important considerations left out. I bet there is.
Another problem is all these speeds have to be very accurate to achieve an accurate total speed

No matter what, the question and any answers you come up with are meaningless unless you specify a frame of reference.

I suppose if could be the visible universe if you wanted to get as big as possible

Ill try
For each one the frame of reference would be its center
for example
center of earth to calculate earth spin
center of sun to calculate Earths orbit
center of Galaxy to calculate Suns and solar orbit speed etc and same for each level above
center of super clusters
center of all super clusters
center of the singularity expansion (curvature of space time)
Dunno

Unfortunately, because all the figures quoted have different frames of references, they can’t be added together directly.

Every particle in the universe is relative to every other particle in the universe !
Gravity dictates the center of the planet.
Gravity dictates the center of every star.
Gravity is therefore your reference. !
I see no problem other than missing considerations in the list which I’m sure there are..
The total can be found by adding vectors of the Earth’s motion around the Sun, the Sun’s movement around the Galaxy, and the Galaxy’s motion towards the Great Attractor. The Earth’s motion around the Sun is small enough to ignore. By coincidence, the Sun’s motion around the Galaxy and the Galaxy’s motion towards the Great Attractor are nearly aligned, so you can approximate the answer by adding 200 km/s to 200 km/s..
There’s a much easier way to find out how fast the Earth is moving. Do you see it?
It’s the Doppler shift of the microwave background radiation.
This was measured accurately first by WMAP and later by Planck.
A recent paper quotes a speed of V/c = (1.2345±0.0007) 10 −3
(aside, 12345, now there’s a coincidence, unfortunately it only works in the decimal system of numbers).
In more usual units, that’s 370.1 km/s.
