I'd recommend getting yourself copies of jazz drummer Louis Bellson's two books of rhythm exercises, one in common time and the other in odd meters. You can then practise your interval exercises and arpeggios in a more fun way than just going up and down an octave in diatonic thirds (or 4ths etc) with constant plain 8th notes. As well as the diatonic scale, make sure to also feel comfortable in: jazz minor (melodic minor ascending), harmonic minor, harmonic major, whole tone, and half-whole octatonic. Practise those scales and intervals with various ornaments (mordent, appoggiatura, etc), slurs, different articulations and dynamics. Consider transcribing a few pieces from other instruments' repertoire. For example, maybe there's a neat flute section in a Rossini overture. You can easily access scores online nowadays for everything that's public domain after its copyright expired.
