I’m asking for suggestions for someone who doesn’t open more than 4 personal cards every two years.
I have a lot of Chase cards already and can’t do CSR/CSP bonus so maybe it’s time to branch out to the biggest bonuses? Don’t have to limit myself to Chase cards

Sorry, I forgot to say. I’m looking for travel benefits, but so far the hotels are not super attractive since I tend to stay in cheaper ones
So let’s go maximum miles route. Above like 2K-3K over 3 months spend I know how to MS at 3%, haven’t researched better ways
I don’t fly southwest much and the CSP just got me the global entry perk recently so it’s not a consideration
You stay in cheaper hotels on purpose? I’ve churned Chase IHG cards several times, and sometimes the intro bonuses are insane, like enough points for 7 nights. Aside from the cards I mentioned, I don’t know much about airline cards. Delta bonuses can be pretty good but the miles don’t go nearly as far as Southwest. But yeah, Doctor of Credit is a great resource regardless.
I stay in them because they are closer to where I want to go in city. Usually the Mariotts are closer to the center and that’s not always where I want to go
IHG might work
Edit: I just went ahead and applied for the IHG card, thanks
