How to return a value based on whether two columns contains values present in other columns

I have four columns to compare against and a fifth one which contains the target value. I need to compare the four columns (2 each) and if they match then return the corresponding value in the fifth column. One of the columns requires comparing using the typical = sign while the other column requires checking if the other column contains part of the text. I tried using regexmatch but I couldn't get the formula to return the values as I'd wanted.
