At MundoSudoku easy starts with 40 clues and medium with 32. Those 8 fewer cells force you to cross-reference rows, columns and boxes, and make notes very useful for tracking candidates.
Well-mastered basics are enough: naked singles, hidden singles and eliminations by row, column and box. Notes help a lot to keep the board under control.
Between 10 and 20 minutes is typical. Experienced players go under 10. The built-in timer saves your best time for this level.
