If it does make the intercooler hotter even by only 1 degree and moving the oil cooler behind fog light DOESN’T result in the oil getting too hot. Then there is zero downside. Considering it is zero extra work or money to set it up behind the fog light vs in front of intercooler it seems like a no brainer.

This is all hypothetical, remember? We have no parameters for discussing what is best for the OP or anyone. We are free to discuss all potential situations, up to and including, the least or best case scenarios. It could be imperceptibly better to move an oil cooler from blocking an intercooler, depending on the scenario, and I could imagine scenarios where it could also be unnecessary to concern one's self with brake ducting, but then again, in another scenario, brake ducting might be just as high or higher on the priority list than maximizing the intercooler's efficiency. It all depends.
We don't really know. Do you? Do you have an example of anyone saying their IATs were higher after installing their oil cooler in front of their intercooler, or has anyone measured the temperature of the air coming through the oil cooler? Even if they did, there may still be enough time and enough of a temperature differential to drop the temperature to the same level regardless. We can guess, but we don't know unless you have something compelling to share. Do you? I'm open to seeing the data and changing my mind.
You are correct that there is minimal differences in extra weight, moving weight to the corner/polls of the car, oil requirements, cost or complexity, depending on what someone ultimately decides to do of course, and you are correct that under many situations, the decreased air flow will probably not effect be detrimental to oil cooling, and if brake cooling is not a priority then it may not matter, so you are correct, under a certain set of hypothetical situations, it could be fine, but the OP seems to want something ideal, and maybe that isn't ideal. It might be fine for you, and it could be fine for him, but it might not be either. We just don't know because the OP hasn't clarified his goals or needs.
The OP asked about doing a top mount intercooler too in his second post, I presume to avoid stacking the intercooler in front of the radiator like he mentions in his first post, so it sounds like he will have extreme cooling needs if he wants to do more than just relocate the oil cooler, yet most STIs, for example, move from a top mount intercooler to a FMIC or V-mount setup, so they can support a much larger intercooler and have the necessary airflow.
