On the skid posts, I see people allowing for a foot of overhang or so. See it in the pictures too.
If we want joists/rim plates on top of posts, why wouldn't we want them on top of the outer skids as well?

I wouldn't cantilever them if it was me, they would be right over the wall.

It can help to shorten spans allowing for savings on floor costs.
I like to move mine in 1 in. to keep them dry and out of the weather.
Footings that are protectd from the weather may be more stable..

You have a point because a foundation is directly under the walls. However, the overhang while using skids attempts to lessen the flex of the floor in the middle by reducing the distance of unsupported joists. The distance in has to be realistic as the farther it is from the edge the greater the chance of sag at the walls.
Also, as Just mentioned, it can keep the wood beams dryer.

Given the sizes of buildings built on skids, how is the cost savings on using 2x6 instead of 2x8 or 2x10 possibly worth either of those risks?
It just seems like a bit of a disconnect wrt to peoples reactions online when I see people evisceration others online when something isn't sitting on a post, yet not a peep in any comment section about this.
Maybe it's different in some manner I am not seeing so doesn't represent a similar problem.

One possible reason is to deter rodents. They seem to love to make there nests in all the cubby holes u create when u don't cantilever.

Yes, it would seem to make sense to have everything directly in line with the downward forces of the walls and bearing walls.
However as stated, keeping posts and skids dry is important and it will extend their lives. (Being close to the ground they would be more subject to rot, etc.)
Also, as mentioned thd stability should improve in a bit from the edges. Underlying blocks, piers, posts that aren’t in direct exposure to runoff pouring down walls might avoid some of the softening of saturated ground. Plus avoiding a situation where any underlying blocks protrude out from under the building wall would have additional advantages - where skids are centred on the blocks to spread the load.

Also if you keep your posts and pads in its easier to install a skirting to close the bottom without anything sticking out
