I have stayed at both Beach Club and Wilderness Lodge. I think the most important thing to consider is if you spent more time at the MK or at Epcot. Wilderness Lodge has a boat to MK and you can watch to Epcot from the Beach Club. You CAN walk to DHS from there but it's a longer walk, so there is a boat to take you there as well. The same is true for Boardwalk, as it is in the same area as Beach/Yacht Clubs.
When deciding between Boardwalk or Beach Club, we looked at pictures of the room and chose Beach Club based on decor since the resorts are similar. The other pro for Beach/Yacht Club is the amazing pool. Though I haven't stayed at Boardwalk, I would imagine the pro might be the shops/dining options. However, you can still visit those while at the Beach Club, it's a very short walk.
From Beach Club to the gates of World Showcase is a 5 minute walk. My family loves this because we spend a lot of time in WS. We weren't huge fans of the boat at Wilderness Lodge, but it is nice to have some transportation variety. Wilderness Lodge is a beautiful resort as well, and I think a little less expensive than Beach/Yacht/Boardwalk. I suggest looking at pictures of the rooms and menus for the food options in order to make a decision. If you're someone who spends a lot of time at the resort pool, then I strongly recommend Beach/Yacht. Good luck!
