AOS with timely sent application may guarantee that you get interview before the DV fiscal year, but if you have ever worked w/o authorization then should go for CP. Since you said TPS , safe bet is to get Advance Parole and appear for interview at KTM, But with this Corona thing , and the embassy has cancelled all the immigrant & non-immigrant interview, your safe bet is to do AOS here. CP has less paperwork and less strict in terms of granting visa (but cannot be appealed if denied) while AOS has more paperwork and can be appealed if denied.
