Okay you got a few things wrong about the speedforce but it's not a big deal since it's constantly changing through every issue. One thing is the speed limit is not the speed of sound, there are certain speedsters who have went faster than the speed of light. With speed force Barry have shown the ability to stop time completely with his sheer speed, in powerscaling terms that is a fest of Infinite speed. Aside from that in flashpoint paradox reverse flash told Barry about speedforce as not just a inter dimensional energy source but as the concept of speed/moving meaning anything that moves is connected to speedforce like how time moves forward and with the help of the speedforce one can control time itself. The speedforce in comics is an inter dimensional energy that exists outside of the multiverse and here it's inside the protagonist meaning he should be able to control time in infinite universes at the same time

Welp it would be awesome if haruto could manipulate his darkness on a conceptual level and hana could have the powers of a million exploding suns

Also another thing I forgot to add was that reverse falsh stated that speedforce is the representation of reality in motion, being the very cosmic force that pushes space and time forward and connects everything including kinetic energy, temporal energy etc, this is also the reason why lightning appears whenever Barry uses his powers and full control over speedforce means not only manipulating time but having control over kinetic and temporal energy and a vast amount of information residing in the speedforce
