At the very least, I would recommend trying to find 4 seats in a row. E.g., if a 3x3 seating configuration (single aisle, 3 seats on each side), I'd try to get seats A-B-C and D in single row.
If a 2x3x2 configuration (2 seats, aisle, 3 seats, aisle, 2 seats), then get A-B and C-D, or D-E and F-G.
If 2x4x2, try to get all middle. If 2x5x2, try to get all middle.
Keep checking seat maps to see what opens up. You can't be picky about trying to sit up front or away from the galley or whatever, if sitting all together is the priority.
