Hey Jesse, I personally like to practice this:

I normally do simple finger exercises before I start these exercises however, just to warm up and loosen up. I really like these as they really teach you the chords well and I like that there is a logical progression between chords as far as finger position changes. I have only been playing for a few weeks, but I have seen tremendous improvements in training my fingers to remember where to go. Some of these I can do without looking even!
Keep in mind I am still very much a Ukulele noob, so take it for what it is worth
Hope this helps.
