Any recommendations for a new credit card that I should apply for that would complement the cards and points that I have?

I am not under the Chase 5/24 rule at this time.

I have:
AAdvantage: 170,000 miles
Delta SkyMiles: 16,000
United Mileage Plus: 129,000
Choice Privileges: 59,000
Hilton Honors: 64,000
IHG Rewards Club: 89,000
Chase Marriott Rewards: 114,000
Wyndham Rewards: 48,000
Chase Business Ink Preferred: 88,000
Chase Freedom Unlimited: 0
Chase Sapphire Reserve: 344,000
Chase Amazon: 0
Citibank ThankYou Rewards: 55,000


Is there a card out there for which you would suggest I apply? Maybe something that would work well with the cards and/or points that I have at this time?



Thanks.

I have a spend of about $6000 coming up and I’d like to apply it to a new card that has a good bonus...if there is something out there that is worthwhile.
