I know some people really like a corridor through the property.
I was never raised with one of those, and have no experience with that.
As a kid my grandparents, uncle and great uncle had cattle ranches, and they didn't use corridors.
Up here in Alaska I have way less acreage and haven't ever used one either.

(not saying that they are bad... just I am not familiar with them)
So.... as a kid in a huge pasture we would drive the truck through while honking the horn... then open the gate to the pasture that we wanted to move the cattle to, drive the truck into the new pasture. Then honk the horn a few more times. Take the range cubes out and pour a few lines of cubes on the ground and get into the truck bed before the herd showed up. Stand in the bed and count the cattle. Get back in the truck, turn around, drive out and close the gate.
To load up cattle you would open all of the gates to the small paddock that was next to the barn and cattle chute. Do the same thing as above. Once the cattle were all locked into the small paddock and the truck out, you could start moving the cattle through the different smaller sorting pens, then into the loading chute.
With the cattle in the small pastures closer to the house (so they were close enough that they could hear my grandfather yell for them), we could move them with my granddad walking first shaking a bucket of cubes, and I would trail in the back making sure no one was lagging behind. Even as a tiny kid, since I was new (I only helped out in the summers), they were scared of me, so would easily move away. They were all well trained to come when called, both by truck horn and my grandpas voice, and the shake of the feed bucket.
Back then as a kid my family had the cattle, a few horses, but no goats. The horses were always kept in the pastures around the house and would come when called.
As a grown-up, I have had milk goats and some horses, and we had no need for sorting pens or a loading ramp.
My baby sister is now on part of the old homestead and has a herd of goats. She keeps thinking about sorting pens and a loading ramp but so far makes do without.
If you want a little herd of brush goats, you might really appreciate a set of sorting pens and a loading ramp, just depends on what kind of animals you have as well as how many.
Anyway.... I set up a picture for you....
This one is my fantasy if I had that property:
The idea of building anything where it might get messed up by flooding .... disturbs me... so all buildings are in the "safe" area.
Yellow is the roads, I tried to follow the existing roads as much as possible, roads get spendy quick.
The barn is the big red rectangle with a road that goes through it. Orange is gates.
With the barn I THINK I made the turn out of the barn soft enough to easily make with a truck and trailer... but that should be looked at super carefully and make sure that the turn is easy enough.
The big house is the big blue rectangle with a small screened walkway connecting it directly to the barn... my kind of heaven.
Tiny blue below is the existing dilapidated run-in. Blue rectangle in the top left corner is tiny house or RV.
So... I set it up so:
6. is sacrificial area so you don't have to worry about losing goats when the UPS guy shows up. Also, This way this pasture can stay way brushier and block the view of the road and help you feel more private.
1. is All by itself so that if you want later on you can make that a rental, with the RV or cabin or tiny house, whatever.
7. is the house and garden and chicken coop and such all in a goat free zone. So, there is a nice sized parking pad at the house, and of course guest parking can all be in section 6.
2. is a smaller "about to kid" pasture, or whoever you want to watch closely, and has barn access.
Pasture 3 doesn't have to lead directly into the barn, they can be fed and watered in the smaller paddock 8. Sorting pens could be put into pen 8 if such are needed.
Pasture 9 can water from the pond, or have access to feed and water through the small paddock 8.
You could shift fences so that pasture 13 also connects directly to paddock 8, or leave as is, and they could use the fixed up run in, and water could come from the house. Pasture 13 could be cut in two and have both parts use the same water up by the house fence.
11 is a spot for shelter, and water and a mineral station. Note that 11 opens onto 4, 5, 10, and 12.
