Replying to you again because I reread your post and noticed you said that you do not really want to churn and do not really want an AF. I feel the same. Here is my (non-churning) strategy:
I have 6 main cards (and a few "sock drawer" cards). I personally don't want to manage more.
CSP - $95AF - I use it very little, but transfer URs from other Chase cards (below). Once the URs are on this card, they can be used for travel. I just opened another one in DH's name(with my support) because there was an elevated SUB. Once my anniversary hits, I will downgrade mine and at some point, hopefully with an elevated SUB, have DH support me to churn this one- then downgrade his. These are the only "churns" I have done/plan to do in about 7-8 years.
CFF - I use this for the 5x rotating categories.
CFU - 1.5x on all spend. Mainly got this for DH since he doesn't want to be bothered thinking about what card to use and doesn't want more than one CC in his wallet. URs also transferred to the CSP. Most of our spend goes on this card.
Amex Everyday - I use this mainly for groceries and a few other things. The MRs transfer to some different travel partners than the Chase URs. I have upgraded to the Preferred with a $95 AF once in the past and then downgraded again after a year because they were offering a nice bonus. I may do this again at some point if the bonus is worth it.
Discover IT - cash back card. 5x rotating categories. I only use this on the rotating categories. I use the cash back to pay the AFs on my other cards. When it builds up beyond that - travel cash.
I also have the no AF Disney and no AF United cards. They get used if there is a good offer on them or if there are 5x categories. So basically only a few times a year.
