Yes, many choices. Strings are a continuing thread at UU. A search will give you as much information as you'll find anywhere.
What it will come down to is:
Each brand or type of string will sound different on YOUR ukulele. The only way to know for certain what sound you prefer is to put the strings on, allow them time to stretch into playing condition, play with them on for some time, then decide if you like them or not. Time consuming, yes. And by then you won't remember what the original strings sounded like in the first place. Experiment some. It will cost you the price of a set of strings or two, but that's part of the game.
Any change of strings up from the standard (GHS) strings will get you different sound. What sound you like is entirely up to you.
Best way to see different strings in action is to find a ukulele group and listen to what those people are using.
Being consistent from one brand to the next when changing strings will produce similar sounding results (switching out an old set of Brand X for a new set of Brand X).
