No 1 C Ionian
Study the intervallic structure of the ionian mode. Jam on Cmaj7 backing tracks and LISTEN to how each note sounds on that chord. Pay particular attention to the natural 4th interval, which is the (potentially ugly but can be beautiful) defining factor of this mode.
This scale holds many more chords than these, with extensions, inversions and every voicing on the neck. Find them all in Fretly
