VAWA Cancellation of Removal (EOIR-42B) is subject to the 4,000/yr cap.
VAWA Adjustment of Status (I-360/I-485) is either not subject to numerical caps or gets counted into F2B (depending if the spouse was a US Citizen or an Permanent Resident).
Honestly, the best solution in this case would be to motion for a termination with the court and then file I-485 with USCIS.
Second alternative is to file I-485 with the court, you first file just the form I-485 (and possibly filing fee, not sure if they want one) with USCIS's Irving, TX lockbox. They will issue you a receipt notice. Then you take the receipt notice and file the I-485 and all related documentation with the court. Then the actual review of the I-485 will happen in court during an individual hearing, with the judge issuing a decision on the I-485. Then once a judge approves it, you wait a few days, schedule an infopass appointment, bring the judge's order and the I-485 receipt notice to the infopass, they will mark off the I-485 as approved, and print you your green card.
Either way, Cancellation of Removal is likely heavily backlogged, so going via I-485 with either USCIS or the court will be faster.
