I did something close to option 1.
I first did a SE IR. I then did the CPL using both SEP and MEP (using SEP for some brought the cost down and using MEP to get my MEP rating). In this CPL 'block' I also did extra MEP time to get the ME-IR. (I can't remember now but I think it's 5 hours + test to get MEIR from SEIR).
My first employer didn't ask anything about it and my current employer (jet) didn't ask specifics either.
