If there was just one place on a car the world's #1 automaker would use oil resistant rubber, safe to say the engine bay would be it.

Never seen oil damage anything, anywhere, on a vehicle in many years of undercoating. Water and salt on the other hand...

Fluid film is lanolin based (sheep oil). It works well but leaves a goopy coating.
Corrosion X HD (turquoise) can is very good, similar goopy coating. I’m not sure the base oil.
WD40 Specialist long term corrosion inhibitor is also very good. It’s thinner and less goopy than the above two. I like it for firearms storage.

I’ve used each for marine outboards, farm equipment, automotive, and firearms in salty sea air. They all have done very well though slightly less than advertising would have you believe. I’ve not had issue with damage to plastics, rubbers, or paints.
I’d say try what’s available in your area and pick the one you like.
