Well, the only general piece of advice in such kind of endgames is to seek a position where if the side with the inferior material is to move it would lose (zugzwang), then find a way to reach this position so it is their move (transfer the move).
Of course, there are numerous pitfalls and one should always be wary not to reach a theoretical draw. When I have more spare time I will look at the endgame you posted and try to identify a workable plan.
Thanks, I abviously got the Zugswang option and it came up a number of times but I was surprised about hard hard it actually was to win with a significant material superiority.
