TL;DR, Bucephalandra (mixed) vs Java Fern
The Bucephalandra (mixed) and the Java Fern come up together a lot when people are choosing a plant, and they are close enough to weigh side by side. Both are happy somewhere around 22 to 28 °C and pH 6 to 7.5, so a single tank can suit either one. The Java Fern is the more forgiving of the two, which matters if this is an early tank, while the Bucephalandra (mixed) rewards a bit more attention. Read the full care notes on each below and pick the one whose look and pace fit the tank you're building.
