Front brake caliper moving side-to-side while riding (video attached) - is this normal?

Bike is brand new.

I’m hoping to get a second opinion on my front brakes from the Heybike community.
As you can see in the attached video, my front brake caliper is constantly moving in and out in rhythm with the wheel spinning. Along with this movement, I'm getting a slight rubbing/scraping noise when I ride at low speeds.

Any thoughts?

Wooden gate suddenly rubbing on the ground and latch side. What’s the proper fix?

My backyard gate has recently become misaligned. There’s now a noticeable gap between the gate and the hinge-side post, and as a result the gate rubs against both the ground and the latch-side post when opening and closing.
My first thought was to sand/plane the bottom and the latch side of the gate so it clears without friction, but I’m not sure if that would just be masking the real problem.
Does this look like a sagging gate, a shifting hinge post, loose hinges, or something else? What’s the proper way to diagnose and fix the root cause?
I’ve attached photos of the overall gate and the gap on the hinge side. Thanks!
