Sigma 100-400mm vs RX10 IV
As a newbie, "Welcome" to the PT forum ~ you will find plenty of others here who love their photography and are happy to assist you in many ways
Your question is a good one - and like many things in life it's a "yes maybe" sort of answer
There is no doubt that the Sony camera with either a Sony or Sigma lens is a strong combination and because of the large-sized sensor will create wonderful and sharp images. The -but- that you point out is both the cost and size/weight of the combination
Have a look elsewhere here for NS's bird images and see how sharp and clear they are ... he is using the sort of equipment you are asking about.
There are many (including me) who use small compact superzoom / bridge cameras with their long zoom lenses and enjoy them very much. As a group of camera types, they offer many advantages plus disadvantages when compared side-by-side to other cameras. Everything today is a series of compromises
The RX10 is similar to some of the Panasonic cameras that I use - so may I offer you a glimpse of what I get ... and your RX10 might produce. Each image below is with the camera at maximum zoom of 30x

2) Pelican travelling past my campsite
ps- for future chatting do you have a 'first-name' I can use?
Hope this helps

I am looking for a sharp, but no-very-heavy, but not-so-expensive telezoom lens. I know, not a good combination
So I guess, bridge cameras will be more of a convenience but sharpness goes to Sigma 100-400mm and more sharpness to FE 100-400mm
I actually shoot on an A7iii and 100-400mm combination and I've been very happy with it. Here are some of the photos I've got.
Any of my pictures on this site in the past few months will have been taken with this lens.
