Hi and welcome to the forum!
I agree with all the above: there's really no guarantee and all you can do is apply and see what you get. Many creditors do have prequal sites that are fairly accurate, but unfortunately that merely provides info about the likelihood of qualifying for the card, not any estimate of how much you might qualify for.
You may want to consider applying for a credit union card. Anecdotally I've often seen people get much higher limits on CU cards than traditional bank credit cards...but that is purely anecdotal and definitely doesn't guarantee you would have similar results.
One card that springs to mind is the Penfed Platinum Rewards Visa Signature card:https://www.penfed.org/platinum-rewards-visa-signature/
However, I'm not
actually recommending it. I don't have the card and have never had any contact with Penfed. I just happen to know that it has 0% APR for 12 months, is a rewards card, and once again anecdotally I've seen people get good starting limits on it.

This is certainly true, but i just wanted to add that if you did immediately close it, it would nevertheless still go on your credit report and remain there for 10 years, would still lower your AAOA, and still count as an inquiry. You may have already known all that, but I just wanted to be sure since some people mistakenly think they can 'undo' an app by closing the card right away; you can't.
Best of luck with whatever you decide.
