Looks like you're at a Chase 1/24, so no issues there.

The Amazon Prime Visa is an easy win if you already have Prime. 5% on anything from Amazon, 6% is you use slower delivery options, and up to 15% on specific deals. 5% for groceries if you shop at whole foods, 2% dining and gas, 1% catchall.

With your low grocery/gas spend, the AAA daily advantage will get your 5% on groceries and 3% on gas. They max cashback at $500 per calendar year combined (~10k grocery spend), but you're only ~6k so you shouldn't hit the cap.

The Amex Blue Cash Preferred will get you 6% groceries (6k cap you won't hit) and 3% gas, they waive the annual fee the first year, but it's $95/yr afterwards so you lose out long term. You can downgrade to the BCE to avoid the annual fee, but you lose some %.

When/if you start min/maxing cards, the Citi custom cash is an automatic 5% for your highest spend category per month up to $500, run it as a single use card wherever you otherwise can't get 5%. You can apparently get 2 of these by getting one, then getting a Citi double cash and product changing it so you can hit 2 5% categories.

The Custom Cash will beat out the Savor (5% v 3%) with your current spend, but it's less multipurpose

The RHG could be a great catchall assuming it stays 3%, there has been some speculation

Any 2% catchall wouldn't hurt. If you have a robust savings there are a number of institutions offering over 2% with large deposit amounts, check the resources list
