I can only comment on command strips (genuine 3m ones) based on my experience in the caravan, so thats composite laminate surfaces. They are designed to come off cleanly (without solvent) when you have finished with them, and that simple fact in my book and experience makes them not 100% reliable. I change mine once a year.
If the back of the mirror is flat then there are stronger fixing pads about*, should be ok if you use plenty of them.
*ie not designed to come off cleanly without solvent, and if its tiles you dont care about the use of solvents later down the line.
