These are from my open-source FABulous FPGA, which was part of the first shuttle run.
It's a small FPGA with 480x LC, 6x MAC, 12x register files and 6x SRAM. The source files are available in the repository: https://github.com/mole99/gf180mcu-fabulous-fpga

The fundamental knowledge you gain from FPGA design can easily be transferred to ASIC design.

As for my personal journey, I started out using the open-source FPGA toolchain (Yosys and nextpnr) with various open-source FPGA boards, such as the excellent iCEBreaker and ULX3S.
I'd recommend learning (System)Verilog or another higher-level HDL that compiles down to it, since Verilog is usually well supported by the open-source tools.

I'll def. take a look through it ^^

If you are the type of person who also benefits from more structure then @matthewvenn 's Zero to ASIC course is also excellent (see https://youtube.com/@ZeroToASICCourse).

How do you know (and specially from where) what exactly to do here in what way for the silicon to work its magic?

I'm also rly. interested to get into silicon circuit designs,, but I'm unsure where to even start.
