To my understanding, we can only see to the point where spacetime has accelerated away faster than the speed of light. The oldest most distant light is permanently out of our reach.

Unfortunately, the universe was opaque for a bit after the big bang, meaning we can't see what happened. If we look back far enough, our telescopes his a wall of microwave radiation known as the cosmic microwave background.

The big bang was the universe starting to expand from a singularity to what we have now. All of what exists now was part of the bang. So you can't see it from any angle because it doesn't have a location, its everywhere.

Yes. However we can't look all the way back to the Big Bang. The farthest back in time we can look with light is the Cosmic Microwave Background radiation or the CMB. After the Big Bang the universe was too hot for atoms to form. Electrons had too much energy. This plasma was opaque to light. Any light that was emitted was quickly reabsorbed and then reemitted. About 370,000 years after the Big Bang the universe kinda instantly everywhere cooled down to a temperature where atoms could form and suddenly light was able to travel arbitrarily far. This light is the CMB. This is a major piece of evidence supporting the Big Bang. No matter where you look you will see the CMB. It covers the entire universe.

To see past the CMB we will need to use something other than light. Scientists are hoping it will be possible to use gravitational waves or neutrinos to detect their equivalent of the CMB but both of those would have originated from the Big Bang or right after it as neither are blocked by plasma.
