Is it correct to say that it is likely there is a lot of inspired writings and things the apostles spoke that did not make it into the canon?
No.
This would reject the sovereignty of God and His promise in Isaiah 40:8; Luke 24:26; Matt. 5:18; 2 Pet 1; 1 Tim 3 and many others.
If God is sovereign and there is no darkness in Him (1 John) why would He keep scriptures from His beloved for 2,000 years?
Also, we have to understand that the apostles did not walk around saying a bunch of "inspired" stuff. The SCRIPTURES are inspired. The Apostles were sinners just like us all and therefore were susceptible to err. Therefore, what we have in our hands are infallible, inerrant, and inspired. These scriptures have been kept by God (Isaiah 40:8) and will never pass away.
So, to answer your question is to start with a faulty premise.
