I've stayed at all of the moderates. If I had to pick again, it'd be CSR for one reason only -- Queen size beds in the remodeled rooms. I am apparently too spoiled to share a double bed. If you can get over that, POFQ is great.
The bus service was a non-issue for us. When the parks were closing, there was generally a dedicated POFQ bus. At other times, sharing meant that buses came more frequently. Either way, not a big deal at all.
The boat ride to DtD is one of my favorite features of POR and POFQ. I greatly prefer the food court at CSR, but that is an acquired taste for sure. Many people hate the Pepper Market. POR's food court is larger and offers more choice than POFQ's, but POFQ's has excellent beignets. No table service restaurant at FQ, but Boatwrights at POR is an easy walk and has good food. Both FQ and POR have great pools. FQ's smallness is nice, and if you want to feel a more spread out environment, walk 7 minutes up the creek and you're in the wide open spaces of POR.
Of course, every Disney resort has something special to offer, and it's hard to go wrong. But you'll enjoy FQ just fine, I suspect.
