THere are so many different brands of strings, it's almost impossible to give a solid recommendation that others won't find lacking. Personally, I like the Aquila strings because they add so much chime to an already percussive and dull instrument by design.
But.. others will say they like their better, so, the best you can do is explore the recommendations and see which fit you the best. Baritone is getting down there, so perhaps what I like in the strings might be totally different in what you demand of yours.
I have tried Martin, Kamaka, Hilo, Aquila personally, as I have had or have ukuleles by each mark, but I find the Aquilas that came on my Big Island to just make it sing and chime beautifully.
