The a7C can be as big or small as you want depending on what lens you use. It has a far more pronounced grip than any of the X100 cameras. So even holding the a7C with a large prime is fine. The 24mm f/1.4 on my a7C II certainly isn't "small", but it is very comfortable to hold. With a 40mm f/2.5 or similar pancake lens, the a7C becomes very compact. Any X100* will be slightly slimmer in height and depth. But you're not putting either one in your pants pocket (unless you wear cargo pants).
In the end it become harder to compare those two cameras because the X100 is always a fixed lens. With the Samyang 24mm f/2.8 AF attached, the a7C is only slightly bigger and heavier than the X100. But you could put a 600mm f/4 on it you wanted to. That's never an option for the Fuji.
I gave up on the X100 line because they weren't weather sealed until the V and VI and the 35mm equivalent focal length isn't my favorite. The X100F was an improvement over the T. Operationally it was much quicker. The bigger battery and better sensor were welcome updates.
There is still artificial price inflation on the old X100* cameras. Used ones are selling for more than I bought a new one for 9 years ago. That really makes no sense.
