Canon M6 has a
24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features Digic 7 processor. On the other hand, Fujifilm X-T4 has a
26.0MP APS-C (23.5 x 15.6 mm ) sized X-Trans CMOS 4 sensor .
One other difference between these two cameras that is worth mentioning is that Fujifilm X-T4's sensor doesn't have an anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the M6 and X-T4 sensor size comparison.

As seen above, Fujifilm X-T4 has a 1.1x Larger sensor area than Canon M6. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Canon M6
or the
Fujifilm X-T4 ,
including hyperfocal distance.
