Typically, the best place to start is the heavy components like transformers, power transistors, power resistors, anything with a heatsink, and with anything that takes physical stress of any kind like a connector, switch or board-to-board wiring.
If you reflow all of that, you have probably covered your bases. Sometimes you'll find the odd loose part that you don't expect, but it might not be the best way to spend you time doing the entire board.
