I'm a bit late to this.. but my recommendations as someone with a very similar brain are:
Oh No, Ross and Carrie - the hosts go on investigations/try out religions, alternative therapies and such like and report back. Tag line 'we show up so you don't have to'. They are brilliant and there are a lot of them. I would recommend the Rythmia, Scientology and Mormon investigations (multi part series all of them) to start with, but the single episodes on various alternative therapies are great for a lighter listen (though none of it's really heavy going). I love this podcast so much.
You're Wrong About - lovely hosts, lots of interesting stuff with a different look on the recent past and social phenomena from the 90s. Particularly love the episodes on misunderstood famous (or notorious) women - Anna Nicole Smith, Lorena Bobbit and Tonya Harding in particular, but they're all good.
Under-understood - fairly light investigations on things that are hard to find answers to on the internet. There's quite a lot of data/stats analysis in some of these, which I feel might appeal to your brain!
They are all chill enough for me to feel calm but interesting enough to be distracted at the same time.
Oh, and I also have a secret love of the Catfish podcast, but have watched the TV show for years because am class act, and I don't know how well it works if you aren't already a fan. I should think it would if you want something really light but somewhat interesting in terms of how humans are.
