Just wanted to chime in with my own data point that might be helpful. We filed my husband’s AOS (from a non-K1 visa) on October 19th of this past year, and his EAD was approved 5 weeks later (one business day after his biometrics appointment) and card received in the mail one week after that. No expedite request or any special circumstances. We were shocked it was so fast, and we personally know another couple who also received their EAD within 2 months in 2022. Obviously it’s very different from case to case and there are no guarantees, but I hope that gives you a bit of hope, at least!
