I think you might be on to something there. I'm in Denmark and Scandinavia have been forerunners when it comes to equality and LGBT+-rights and such, so perhaps the use of the "fem" in the term feels undue for my cultural background.

There’s surely some issues still to work on with gender equality, but the main big ones have been pretty much solved as best we can.

I think this very much depends on where you live. I'd say that even in Denmark, which is very well ahead of most of the rest of the world, there are still lots of gender equality issues. We've only "solved" them in the sense that the laws are fairly equal (not equal to the extent I would like it, but almost), but the culture is still somewhat unequal. Women still take much more parental leave than men do, for instance.
