Our two favorites to split are Wilderness Lodge (either BRV or CCV; we own both) and AKV (preferably Jambo, but we do also like Kidani, especially for the extra bathroom). This puts us close to the Magic Kingdom for BRV/CCV (we love taking the boat to the MK) and Animal Kingdom for AKV, our two favorite parks. And they are both about equidistant to Epcot and Hollywood Studios.
We do also now own at RIV, so sometimes we split one or the other or both with RIV, to give us that easy Epcot and Hollywood Studios access (though I'd rather own Beach Club, personally, but we bought RIV in summer 2022 for around $145/point after incentives, and I don't like that BCV is ending in 2042 and costs so much, so RIV it is!). This means sometimes we split 3 resorts, and sometimes 2, depending on what we want to do during our stay. At present, it actually tends to mean we do more shorter trips and pick a resort close to what we want to do. At the end of August/early September, we are doing a split stay between CCV and AKV. In November, we are doing RIV for Food & Wine.
