I'm not interested in translateling just the literal meaning of FYI. I'm
interested in if there is a phrase that fits the same nuance.

Some English examples.

To Spouse: "Oh, FYI, Jill is bringing the wine".

To Co-Worker: "FYI, that meeting has been moved to 4pm"

To A Friend: "FYI, the Toyoko-Line is closed for repairs so you should
probably take the Meguro-Line"

"FYI" is a very casual phrase in the situations above. Maybe "ところで。。。。”?
Although I don't know if you can use "ところで。。。” at the start of the
conversation. Every example I've been taught is always in the middle of a
conversation when wanting to suddenly switch topics.

I came here because I typed "FYI" into Google translate and it said "ご参考までに”
was the "community verified" translation but that seems not to fit the same
nuance as FYI.

How to translate FYI into Japanese
You could also use `ちなみに` aka "by the way" in the same context as FYI in a
casual setting.
