What I usually do is going through the puzzle doing snydernotation first (marking when a number can only be in 2 places in a box)
Most easy puzzles can be done with only that, then when it stops being fruitful I fully mark the puzzle up and start looking for things in roughly this order:
That’s at least my basic rough order of going through solving a puzzle.
