@O.Jones, what is important is that you get any desired request for room location into MS quickly because you are close to arrival and it has been mentioned that they start assigning rooms a week before any given arrival date. See this map of SSR
www.themeparkprofessor.com/wp-content/uploads/2020/12/SSMap.pdf.
As noted above "Preferred" areas are Springs and Congress Park. "Standard" are Grandstand, Carousel and Paddock. The division between preferred and standard is simply location as the buildings and the type and size of rooms everywhere are essentially the same. Springs puts you close to the main themed pool, Carriage House (the front desk and bell services building). Artiste Pallet (quick service restaurant), Spa and Fitness Center, tennis courts, and a fairly short distance to the golf course clubhouse building which also has SSR's main restaurant The Turf Club, which also has a bar. A room request to consider for Springs is higher floor for better views.
Congress Park runs right along the lake front, has a a quiet pool, the shortest walk from SSR to Disney Springs, a number of rooms that can actually provide some good lake views looking over toward Disney Springs, a lake front walking path, and is not very far from the Springs area. If you choose to make Congress Park your request, and you have reserved a dedicated 2BR, you might also consider asking for a higher floor room ending in numbers 21 or 27 (that is the last two numbers for the rooms not the entire room number). Those are all dedicated 2BRs in the center of each of the Congress Park buildings and have fairly decent lake views.
Be aware that the bus to the parks stops, in order, at Grandstand, Carousel, Paddock, Congress Park, Springs and then to the park. For Springs, more so than Congress Park, there is some risk, particularly during the early morning rush hours, for ending up with standing room only, and even possibly having to wait for another bus.
