My favourite is Philosophy Bites which has been going for 16 years, run by Nigel Warburton and David Edmonds.

These are short, around 15 minute, discussions on a philosophical issue that can often lead me to further reading and listening e.g. recently, Keiran Setiya on Loneliness. That lead me to his own podcast Five Questions (which you can find on Castbox along with another 259,000,000 volumes of audio content!).
In the PB discussion, I was struck by what what Warburton and Setiya had to say about the relationship between humans and pets.
That lead me to listen to Tim Crane talking about Animal Minds.
(Anyone who has read Bonnie Garmus's novel Lessons in Chemistry will be familiar with the loyal "thinking" dog Six-Thirty.)
For a broader range of subjects and a longer listen, Melvyn Bragg's In Our Time is hard to beat imo.
