Maurice Vaute's 'Barque d'or' is a lesser-known Romantic salon piece evoking the imagery of a golden boat. Its lyrical, flowing lines reflect the aesthetic of late 19th-century French character pieces.
Mastering the undulating left-hand accompaniment is essential for the barcarolle feel.
Comparable difficulty and character — good candidates for what to learn next.

You should be comfortable at Henle level 3 — meaning you can already play level 2–3 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
