Your priority date is when you submitted your application to the USCIS, that is your i130 petition. Which I believe is 23 May 2023 as you stated above. NVC does not give a priority date, you only have one priority date. As you have been approved now by the USCIS, NVC will send you a welcome letter, hopefully before weekend, after which you will be asked to make payment for your Affidavit of Support and IV, after making the payment, NVC will have to confirm your payment before you and your spouse can proceed with submission of your documents which takes roughly a week, then you will be given access to fill out your DS-260, Affidavit of Support and Civil Documents. After you have submitted your application, NVC will now accept your documents within a week, and that is when you are officially Documentary Qualified. While USCIS gives Priority Date, NVC gives Documentary Qualified Date which is what the embassy will use to determine your interview time. NVC process takes roughly 3 weeks to be documentary qualified. Congratulations
