Both Drivers and Front Pass windows do this, sound and move very weak at very top and bottom?
2010' Is it showing wear and age, or is this normal?

I haven't noticed it on the way down but mine also slows down at the very top. It's as if there is more resistance once it gets up there. Two vehicles doesn't mean that it is normal, but yours isn't the only one and I haven't had any actual problems with the window regulators.

I want to say all four of my windows do this, the exact same way. Perhaps it's a safety feature?

The sound it makes seems like it's struggling, but I think that's just because it cuts power at the top.

At first I was worried when one window did it but when I noticed the others were exactly the same my worries went away.

It's normal.

I've never noticed it at the bottom, but mine does that at the top. I think I read that it was an "anti-pinch" feature since the windows are auto-up.
