As others have stated VB, HHI and Aulani all have full beach access and you can swim in the ocean.
At WDW swimming is prohibited for health reasons.
However, BCV has a beautiful beach and the best pool at WDW. But that pool is shared with BC and YC and although pool is large it does get crowded. In fact the entire resort area is pretty busy.
BLT has access to a small beach that could keep some toddlers happy. But it is not an attractive beach. WL has a beach too, but I've never really walked it.
SSR has a very nice feature pool and second one is being built. The slide at BLT is very popular with kids and adults, but the area surrounding the pool is on the small side, on busy summer days, it's hard to find a chair. But you can use the CR pool when staying at BLT. The biggest complaint with BLT is that in the summer a lot of the pool area is in the shade in the afternoon. The water play area is a splash area that kids always love. However, the water play area at Kidani's pool is the very popular with DVC families but some complain that there isn't any shade around the pool. The feature pool at BWV has a slide that comes out of a clowns mouth. And some kids think it's funny to have the clown throw you up and others run in terror from that scary clown. The pool is large and has a kiddie pool, but no zero entry. Plenty of area for shade. The feature pool at VWL is shared with WL and is really attractive, but it seems to get crowded easily. I don't really know about the pool at OKW, except that I believe it does not have a zero entry.
The pools at Jambo House, AKL; SSR and WL have good access to a quick service restaurant. BLT, Kidani, and BWV have access to a pool bar with a limited menu. I don't know about dining at the pool at OKW and BC/Storm Along Bay. Hopefully someone else will fill you in on those resorts.
Whew, hopefully I covered all of the resorts.
