These particular words haven't evolved in any meaningful way in the last century or so. If anything socialism now refers exclusively to revolutionary/militant utopian socialism whereas it had more varied meanings long ago. That's probably largely an artifact of the fact that socialism since the early 1900s has mainly been promoted by socialist countries after a revolution.

Go on a socialist forum and ask them what they think about markets or mixed economies. E.g.

It's harder to search other socialist forums like the darknet ones, but you see the same patterns there
