Fujifilm X-T100 has a
24.0MP APS-C (23.5 x 15.7 mm ) sized CMOS sensor . On the other hand, Fujifilm X-T30 II has a
26.0MP APS-C (23.5 x 15.6 mm ) sized X-Trans CMOS sensor and features X-Processor 4 processor.
One other difference between these two cameras that is worth mentioning is that Fujifilm X-T30 II'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 X-T100 and X-T30 II sensor size comparison.

Fujifilm X-T100 and Fujifilm X-T30 II have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the 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
Fujifilm X-T100
or the
Fujifilm X-T30 II ,
including hyperfocal distance.
