If you have a 'hub'--use a rubber dough nut----

If you have a cut pipe--a rubber Fernco type boot with hose clamps works well.

Post a picture if you can that will get you the most accurate advice.

If you use that flange, you need to bust out the floor, lower the CI pipe to the proper height and use a PL x CI no-hub band to join the flange to the pipe. Then replace the removed concrete and anchor the flange to the floor
Why an offset flange?

Old house, the toilet is at a wierd distance from wall , whats would you suggest to just to install toilet easiest

These toilet replacement flanges; manufactured by Oatey, are made to push into a 4" cast iron drain or plastic pipe and seal against the internal diameter with a rubber gasket. Although they make a flange that fits inside a 3" pipe, they are not permitted because they reduce the internal diameter.
You can try this, I have never used one before but I have seen them. It is difficult to tell the size of pipe you have there, it looks like 4" but the flange you have looks like 3". Just a suggestion.

How far from the wall to the center of the pipe?
