Amex approved me for the Gold card without a FICO score, so I'd go with that card if it fits your spending.
The pre-qualifications are pretty solid from Amex, at least for me. In my opinion if it gives you a specific APR, like 14.99%, and not a range, like 12.99 to 29.99%, then is it definitely solid.
If you get an Amex, alway treat like a lady, because Amex has a long memory.
I had a previous collection with AMEX back in 2016 that I paid 75% off and settled. I have one current collection on my report that I haven't paid off and my score at the time was 620 Experian. I did the pre qualify and got offered the Delta Gold and took it with a $1000 CL. So IMO the chances are probally good still if you got pre-approved.
