I've ran into this situation multiple times at my current and previous jobs. I really want to avoid Windows and use something better, but I can't live without two external monitors.

On Windows, it "just works". I don't have to do anything.

On Linux (I tried Linux Mint today) it doesn't work. First, it only connected one of the monitors, the other one did not register. Then I switched to a different cable from the computer to the docking station and it connected both screens - however, they were locked to 30fps. I could not make them work at 60fps (and this is a major dealbreaker, I cannot live with 30fps).

This isn't really a tech support question, I'm more trying to understand what fundamentally causes this situation. Why is Linux still struggling with pretty basic functionality that Windows does with zero setup? Is it the vendor of the laptop and docking station that aren't properly supporting Linux? Or is it some other problem?

I know, I did read your entire post. As I said, it's not unheard of for Windows drivers to be more fault tolerant in suboptimal conditions. For example: Windows GPU drivers in the early days of HDMI 2.1 needed a lot of tuning for tiny oltage adjustments to ensure signal integrity if your cable wasn't exactly up to spec, basically compensating for a "bad" cable, whereas the Linux drivers at the time didn't really try to do that. This doesn't have to be the case for you, but it should be relatively easy to test.
