AOS ADVICE!- I-130 online receipt needed before mailing I-485 — how quickly can I get it?

Hi everyone! I’m married to a U.S. citizen and we’re filing for adjustment of status.
Our plan is to file the I-130 online first, and then mail my I-485 package separately. I was told that I need to include the I-130 receipt notice with my I-485.
My concern is timing because my F-1 grace period ends September 17. We are planning to file the I-130 online around September 15–16, and I’m planning to overnight/expedite the I-485 package on September 16.

My question is: After filing the I-130 online, is there an electronic receipt/notice or receipt number that becomes available quickly in the USCIS online account that I can print and include with the I-485? Or do I have to wait for the physical I-797 receipt notice to arrive by mail?

Has anyone recently filed an I-130 online and then mailed an I-485 separately? How quickly did you receive/get access to the I-130 receipt number?
I’m trying to avoid delaying the I-485 because of my September 17 deadline. Thank you

Also if what the best form of payment, we have a card, what form do we use if we’re paying by card?
