What kind of sound are you looking for?
These are how I hear ukulele strings. They are strictly my personal impressions, I play only tenors, and I know others hear them differently:
Nylons have a crisp, almost barking sound that I find a little harsh. Yet I have heard people play some exquisite, soft and lovely music on them. When I think of Nylon strings, I think of a traditional soprano "Hawaiian" sound.
Fluorocarbons have a softer, more chime-like sound. Some sound almost guitar-like. Others a mellow or dark sound. I think, in general, they are more nuanced than Nylons. But, I have heard players get an almost steel string sound on their electric ukes from some fluoros.
Aquila Sugar strings seem like they are a little of both. Nylons with a softer, rounder, somewhat Fluorocarbon tinged sound.
Wound G & C strings have a "Whang" sound to me. That can often overwhelm the other strings. And they wear out quicker than plains. I have heard fantastic fingerstyle playing where the harshness isn't at all apparent.
These are rough, very general descriptions. The instrument itself affects the sound. And a string that sounds great on one instrument can sound dull and plonky on another.
I think Living Waters Fluorocarbons would sound great on your roosebeck baroque-a-lele. They have a sort of dulcimer or mandolin-ish sound that I find very musical and lush.
