AES-GCM-SIV synthesizes the internal IV. It derives a hash of the additional authenticated data and plaintext using the POLYVAL Galois hash function. The hash is then encrypted an AES-key, and used as authentication tag and AES-CTR initialization vector.

The IV prevents the appearance of corresponding duplicate character sequences in the ciphertext. The basic idea of an IV is to prepend a bit of random content to each message, in a principled way. How this works precisely depends on the mode. (The core AES operation only works on 16-byte blocks. A mode is a way to extend this to longer messages.) AES-SIV and AES-GCM-SIV are two SIV variants built from AES. Since SIV modes make the encryption IV/nonce content dependent, two different messages with the same message IV will still result in different AES-CTR XOR streams. XORing their ciphertexts no longer accomplishes anything. First, there is no such thing as CTR or CBC with "no IV." You are likely just using all zeros as the IV. There is always an IV. (CTR calls its IV a nonce.) The IV of AES is always 128 bit regardless of the key length, meaning this leaves 32 bit (128 bit - 96 bit) for the counter which gives CTR (counter mode) its name.

Note that after AES-CTR encryption the initial vector (IV) should be stored along with the ciphertext, because without it, the decryption will be impossible. The IV should be randomly generated for each AES encryption (not hard-coded) for higher security.

Excuse my ignorance, but I'm not certain as to what the IV length should be when using CTR mode on AES-128256.The best answer I've found is that it should be equal to the block size, which would be 128 bits, but most of the resources indicating that are slightly dated or poorly elaborated.
