When you get much nearer to departure then you may want to look at the options, at this stage it's too soon, and I suspect there is also a fair chance that the flight will go out completely full, just the way aviation is quite busy at the moment. Full flights, with standby passengers, won't lead to empty seats anywhere. But as a general rule, people love to sit near the front, so seats towards the back of the cabin are usually less preferred. The TS thread above has more information.
