I used to be really into discovering beers, but I usually just drink Founders All Day IPA these days, with a German Pilsner as a backup. There are only a couple months out of the year here in Florida where I'd want something that over 5%, though.
Founders All Day IPA is a solid go to. Other session IPAs/APAs I enjoy are Notch Left of the Dial, Lagunita's DayTime, Harpoon Rec League, and Zero Gravity Little Wolf APA.
But, to your point, even Cigar City's flagship IPA is 7.5% and way too heavy for the climate. We find it very ironic that a brewery from Michigan makes a wider, better range of refreshing beers.
I hope they're able to stay open after all of this, but my favorite brewery in the area is Flying Boat (St. Pete). They don't distribute, but their beers are consistently refreshing across styles. It's located at the end of a quiet, suburban neighborhood, so you you can have a beer outside and watch the neighbors mow their lawns.
