Stupid question

The head and tail lights on the 2019/20 Mazda 3 look very similar to the sets my 2016 came with. are they interchangeable? If so, How difficult would it be to wire in the led inserts?

If you do not get a response, you could call the parts person at a dealership to see if the part/assembly numbers are the same.

They are different generation vehicles, and I doubt they would swap over from 1 generation to the next without modifications to body.
