I think CBR would be great for you! The pool area is perfect for your toddler. Small slide, zero entry, height restricted splash area that keeps big kids out so little kids can really enjoy, two hottubs and you can see the high up fireworks of Epcot (which is right near to you) from many areas around the resort.
CBR is large, but honestly, all WDW resorts are large. POFQ which is the "compact" moderate has 7 buildings and 1000 rooms! You can pay for preferred at CBR which will give you a room very close to the central area where the food court and pool are. We don't find the need for that but our kids are older. The furthest out room at CBR is maybe a 5-7 minute walk at a leisurely pace. Unless you book a "pirate" room that is. Those rooms are closer to a ten minute walk. But those are a separate booking category, all other rooms are closer. I do suggest that if you book a non preferred room, take a stroller for sure so that your dd won't be tired out from walking. But that goes with any WDW resort since again, they are all large. Even the one building resorts like AKL, WL and Boardwalk have lonnnnggg hallways!
I think CBR would be perfect. We like the values but after 10 stays at them, we have decided our value days are over. They do tend to be nosier and while the themes are fun for kids and adults, a moderate has the nicer grounds, pools and more peace and quiet. And larger rooms with larger bathroom areas.

Its wonderful and really shows you the whole resort including the pool, grounds and room interiors.
I forgot to add that there are several nice playgrounds at CBR, including one in the little island of Caribbean Cay. I know POR and CSR also have playgrounds, for the life of me I can't remember if POFQ does. The values also have playgrounds. I think Caribbean Beach has the most though with four total and that new one on Caribbean Cay is really nice.
Another big plus for CBR is its central location. Its particularly close to Epcot which is why it has such nice views of the Epcot high up fireworks. It does have seven bus stops but the good news is that each "village" has a covered bus stop nearby as well as a quiet pool. We had great bussing at CBR but bussing can be hit or miss with any resort. I am hoping for another good bussing experience next month when we stay there for the second time!
Any WDW resort will be great and have a fun pool and theme your daughter will enjoy. But I do think CBR or any other mod would be a great choice since they offer a lot of nice amenities and a lot of peace and quiet for mom and dad over a value. I love and have stayed at all of the mods and do think CBR's main pool is the best for kids the age of your daughter. Good luck with your choice!
