You are close on this.
Most 12" rough toilets have 3/4" behind the toilet, thus they will mount with 11.25" from the wall, measured from the wall to the center of the drain.
Sometimes you can move the bolts out that extra 1/4" and install the standard 12" toilet anyway.
If not, the other option is the 10" toilet. Every manufacturer has the 10" option. Some use a thinner tank, sometimes a modified bowl to 10" and then there are those that use an adapter to change the rough distance.
I would not consider an offset flange for your bathroom. They don't work well, and the expense of ripping up your floor would be way more that buying the right toilet for your home. There are no plumbers that like offset flanges in the floor.
TOTO now has a 10" dual flush at the factory.
