Ok, I doubt any human can actually solve it. For the answer, use Stockfish.

Well, I cheated - as I often do on engine puzzles . Still, I hoped there would be some exciting finish but I couldn't find one. Only landed in endgames where white is a piece up and needs to keep its last pawn. Is there a neat tactic I missed?

No, it's as you say. There's one sequence in which white comes out up a bishop and then wins with his pawn. Stockfish at high depth gives White at least a +3.3 advantage at the starting position, but even the slightest inaccuracy in the first 10 moves will bring it to equal, with perfect play.
At the highest lvl, the game is often decided by a single move in the middle-game which gives one player a decisive advantage in the endgame; though admittedly, I don't know if there's any human that would win this position against stockfish.
