So change the website theme to light mode? I use dark mode, and am happy when websites are served in dark mode (and I think the majority are this way). I think you're likely in the minority, and the easy fix is just to switch the websites you use to light mode.

The trouble is that `prefers-color-scheme` is set at browser or system level. In order for a website to use a different colour-scheme, then they need to add functionality with Javascript in order to be able to load different styling at user request.
I wish there were some URL-based rules you could set in the browser settings (I expect there are addons to do this, haven't looked though!).
What if the website does not provide a toggle to control to control this? I wish there was a browser preference to control prefers-color-scheme (which it sounds like new FF does!).
I don't really care that I'm probably in the minority of users who think or care about this. It doesn't make how I feel any less valid.
