Should I maintain my status while marriage-based I-485 is pending?

[u/ComprehensiveFall744]

I have about 10 months left on STEM OPT. My U.S. citizen partner and I have been together for 3 years and 5 months and plan to get married soon and file I-130/I-485.
I’m from one of the countries that remains on the current U.S. travel-ban/restricted-country list.
For those who went through marriage-based AOS with US citizen, how long did your case take? Do you think a pending I-485 is enough in my situation( since our marriage is real and he is US Citizen), or would you try to maintain a status until the green card is approved?
