my current cashback setup and roadmap

I am a big fan of cashback(CB) setups, despite this I don't like optimizing every single cent, this is probably due to me being a low spender in general. I feel like a bit of an outsider in most credit card communities because I don't see people like myself, Right now my CB setup looks like - Citi Double Cash 2.22% Everywhere - Citi Custom Cash 5.55% Grocery - Citi Rewards+ 10% TYP Redemptions - Chase Freedom Flex 5% Rotating, 3% Dining, 3% Pharmacy - Discover It 5% Rotating - Amex Blue Cash Everyday 3% Online Retail, Gas I want to add the US Bank Cash+ for its Utilities and TV/Streaming/Internet categories, my phone provider (GoogleFi) typically codes as streaming so this card is going to fit right in. Beyond that however, I feel like I will round it off with the Ralphs or Kroger card from US Bank. the Rewards+, Amex BCE, Cash+ and Kroger/Ralphs Cards all would never even have to leave home, so while I normally think 8 cards is too much for me, this would have nearly the same mental energy, if you will, as a four card setup, meaning I could even add another card to keep tabs on 5, and sock drawer 4, what that card would be I am not certain yet, right now the leading options are the US Bank Altitude Connect or the Smartly card, I will decide when I am closer to that point
