Service Feed Through Basement Wall
I am pretty sure this is the meter socket we’d be using.

The basement wall is 8′ high and would have 3 to 4′ exposed where this would go. I know this does not have to be spot-on, but how far down from the top of the poured wall should the mason put the sleeve through which the service will pass to the panel?
I want to jot something on the drawing . . .

Check the NEC, there are height requirments for meters and panels and it looks like this one would be to low (the exterior one I mean). Run the conduit through, with a 90 degree elbow and go up the wall into the meter, this way you put it where you want for now.
The drawing is not to any sort of scale, but I "see" what you mean.
I would first check with the utility provider and see what their meter requirements are. They vary widely from place to place. Usually it's the locals call. Lately, a lot of utilities have been installing remote read meters, so they don't require them to be up so high. Some require them to be at eye height or above snow levels.
In any case, the bottom of the pedestal has to be at least 18" below the surface ( at least that's what it is where we work).
Then you have to put your service panel at your preferred height in the basement. Figure those two things out, and you should know where to put the sleeve.
Check with your local power company. They will provide you with a detailed drawing of what they require, including how they want the meter base attached to the wall, be it concrete, block, or stud wall. Minimum and maximum heights are also included.
Your drawing shows an 8' poured wall, with the meter base mounted on it, near the top. An inside panel height (top) of 6' would mean that you only have 2' difference between the inside and outside equipment. A sleeve at 7' OFF would be in the neighborhood of the bottom of your meter base. Makes for a short wire run between the two, but a bear to get wire into nearly back to back LB fittings.
Most likely, you will end up mounting the meter base on the framed part of the wall above the foundation. If that is the case, there is no need to sleeve the poured wall. Just come out of the bottom of the meter base and go through the rim joist and down to the panel.
Now would be a good time to consult with an electrician, even if you think you are going to do the work yourself. A small consulting fee will net you advice on you local requirements and save you a lot expense from reworks that fail inspections.

I would try to keep any wall penetrations at least a foot or 18" above grade if possible. You never know when some idiot decides to pile up dirt or mulch along the walls, thus giving a pathway to water to come in.
Not that we have any of those idiots around Columbus...
