When attempting to learn a key (also called tonality), I find it's important to learn as much material from it as possible : intervals, triads, seventh chords, "triads over bass" chords and other relationships.
If you didn't do so already, please read and play through The Advancing Guitarist by Mick Goodrick.
A great "formal" way of learning all the seventh chords (and triads) present in a key is going through cycles : they consist of systematic root movements covering all the chords of the key.
As far as seventh chord, goes the key of C major contains :

The motion of this progression is "cycle 2" because each new chord is a diatonic second up from the previous one...
The question is :
In how many "patterns" could we play
those same chords from above?
Six !!!
We have cycle 2 (above), cycle 3, cycle 4, cycle 5, cycle 6 and cycle 7.
So, here's a reference chart for diatonic jazz chord cycles :
