Weight is another important factor especially when deciding on a camera that you want to carry with you all day. Panasonic G100 is significantly lighter (968g ) than the Fujifilm GFX 100 which may become a big advantage especially on long walking trips.

Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since Fujifilm GFX 100 has a Medium format sensor and Panasonic G100 has a smaller Four Thirds sensor, Panasonic G100's lenses for a similar focal length and aperture will generally be lighter and smaller than the Fujifilm GFX 100 lenses.
