Which one would you choose? FT position without much interest in the field or a traineeship that are unrelated to my degree field?

I have recently just graduated from University and have been offered an FT position prior to my internship with the company. However, I don't really have much interest in that field and likely won't be staying for more than 2 years. I have also been applying for traineeships that are unrelated to my degree field.

I have been thinking if accepting the traineeship over the FT position is worth, as traineeship doesn't confirm a position in the company after 1 year of training.

Thanks.
