If my recipe shows that my OG should be 1.079, but my OG was 1.081, do I still need to try and hit the recipes FG of 1.010 or do I now shoot for a FG of 1.012?
Two points is not going to make or break your brew. Still aim for the fg of 1.010 but if it finishes at 1.012 then I wouldn't stress over it.
Did you also make sure your hydrometer/refractometer is correctly calibrated? 2 gravity points is close enough to say it could be a temp or cal difference...but again don't stress
Make sure you corrected for temperature. 2 points is nothing don't worry about it. And don't worry if you don't make it to 1.010. You may not make it if your wort is not fermentable enough.
