Optimum block size is determined by channel bandwidth and delay through
the channel.
Not by your code.

that was not the question. does having a fixed block size regardless of
the length of the key or plaintext provide an avenue of attack.

If you are encrypting each block with the same key it is.
But most encrypt at a higher level over long lengths, some continuously, and
then the encrypted data is then broken into blocks for shipping out.
