Depends on your preference and the complexity of the design.
Less "stuff" in a sketch is less busy and easier to see what you're doing. (less dimensions, constraint icons, etc.)
For something like this it's probably a toss up, but, I'd tend to pad the raised panels, then drill (pocket) the holes.
In fact, I'd have started with a big flat panel, pocketed the rectangular openings, padded the raised panels, then pocketed the holes.
But, that's just my way...
