Jordu huh?

I suggest Rhythm Changes and 12 bar blues.
In ballad, medium and up tempo styles.
Also in swing, Latin, bossa, samba, salsa, boogaloo, funk, Debussy style, Calypso, etc... Piano LH: stride, walking bass, half note bass, arpeggios, 5432 fills in left hand, syncopated stride. I do all my warm up katas across those left hand textures, styles and tempos.

Then perhaps a big standard like Autumn Leaves.
