2015 Prius C making strange noises

I bought this car used at 69k miles last year, and it's at 91k miles now. The work done since then was replacing the front brake pads, adjusting suspension, and regular maintenance. Asking on reddit to get a high-level opinion and save for repair costs. (Headphones on both ears recommended).

For the first video: Ignore the aluminum crunch sound as those are the cheap wheel covers. The noise that bothers me is the old chair squeak sound that appears when I lightly apply the brakes at lower speeds. This noise was not there when I first bought the car and started happening randomly within the past few weeks.

For the second video: This noise also popped up recently, it is a high pitch squeaking/chirping sound (ignore the birds). The sound speeds up along with the acceleration. I suspect it could be a worn serpentine belt due to the pitch but would like to know what other possibilities it could be. Thoughts?

 

Typo, by wheel covers I meant hub caps, and the "aluminum crunch" sound is more akin to a crushing cans sound.
