If I understand it correctly, we measure time by how fast light passes, or something similar to that. Now if the universe expands faster than the speed of light, would that mean that the universe ages faster than earth, or maybe slower than earth? Maybe this doesn’t make sense but I have a gut feeling that there’s something to it…

Simply put, space time stretches with higher concentrations of *stuff*. The more *stuff* there is in one place the more time will dilate. So where there is no *stuff*, time goes faster. And a lot of *stuff* can make a black hole where time for all intensive purposes has to stop. Astronauts age slightly faster because they are farther from earth which is made of a lot of *stuff*.
The “observable universe” is our limit as to how far we can see into space. At some point the light being emitted from *stuff* cannot outpace how quickly that *stuff* is moving away from us. So the *stuff* appears younger to us than it actually is.
At the outer limits of our observable universe, relative to us, that *stuff* looks like it’s moving away at the speed of light. But that *stuff* is not moving THROUGH space at light speed. The actual place it exist in is getting farther so no laws of physics are broken.
