Recipes for daily city/street photography

Hey everyone, I’m looking for some advice on daily street/city recipes (Context: I'm visiting London over the weekend).

I’ve been using Osan Bilgi’s Summer Chrome and Classic Cuban Negative lately. Summer Chrome was amazing for a trip to Turkey last summer, but outside of that "summer/vacation" it feels a bit too warm / orange imo. I really liked CCN in Japan last year, though I feel like it works best in high contrast conditions.

I also tried Reggie’s Portra as it's suggested a lot for a more neutral / versatile recipe, but to me it always felt a bit boring and flat (though that might just be my lack of skill).

Does anyone else feel the same about these? And more importantly, what are you using on overcast or "gray" city days? Do you have any suggestions for other recipes I should consider?
