I'm more of a tea drinker, but my spouse really likes the decaf beans from Saltwinds Coffee Company. They're a Canadian east coast company. https://www.saltwindscoffee.com/product/decaf-ocean-fresh/?v=34f67f9dfb46
That and Kirkland decaf are his go-to's. Like OP, he also can't have a lot of caffeine anymore.
Not much point in running from it, you're already getting wet if you're caught out in it 🤷♀️. I'll run if I hear thunder though, don't want to get electrocuted.
