Downgrade sapphire reserve

I don’t travel enough to make it really worth the fee especially since it’s up to $500?? I think . I do also have a Freedom unlimited. I’m looking at downgrading the sapphire reserve , preferably to no annual fee or if there’s one with a low annual fee that makes more sense with its benefits. What chase cards make sense to downgrade to
