I've heard of this distinction within Tibetan Buddhism, I'm not sure if it exists elsewhere.
The three types of bodhicitta are king like, ferryman like, and shepherd like.
King like is like Amitabha Buddha. The bodhisattva attains enlightenment ahead of everyone in order to lead others into enlightenment.
I'm not familiar with a Buddha that represents the style of ferryman ferryperson, but this type achieves enlightenment alongside others.
And then shepherd like bodhicitta where the bodhisattva leads others to enlightenment ahead of themselves. Avolokiteshvara is this kind of Buddha.
I kind of feel resonant with the second one.
