I had a similar design garage at my previous house. Mine was 24' deep x 26' wide and my "man door" was on the side. I also had 9' wide o/head doors. My lift placement was similar to yours, but with the reduced width, my lift was about 6" closer to the side wall. It was tight squeezing through, and I couldn't roll by hydraulic jack between the lift post and the side wall. Make sure you have at least 2' (preferably a bit more) between the lift post and side wall. Looks like you have the lift centered on the opening which is a good idea, but if you shift it a few inches left or right it shouldn't be a big deal.
Regarding placement of the lift front to rear - looks like you have calculated 23' 4" inside space. If you have 24' depth outside, with typical 8" thick frost walls, then your inside space is about 22' 8". Keep this in mind as you do your calculations. I don't live in that location anymore so I can't measure my lift placement front-rear, but I did have an asymmetrical lift (which I would recommend). I do recall when I calculated my lift placement that I took the 22' 8" depth, subtracted 4' (workbench and walking space in front of the car). That left 18' 8". I then "centered" the lift "center point" around 9 1/2 to 10' from the o/head door. This actually puts the lift posts about 12' from the o/head door which is about where you have yours.
Note - if you rarely work on long vehicles like pickups, err on the side of moving the lift back toward the o/head door - you'll appreciate the extra space up front by your workbenches.
