https://archive.md/ gets around way more paywalls. Highly recommend it.
watchreplay.net works for NBA. Haven’t ever found a site that works for other sports.
I think you’re pretty unlikely to find anything else. I doubt it’s worth the effort for sites given people want their sport live.
I’m into tennis and I’ve had to subscribe in order to watch replays outside my timezone.
The fact that the sites are often Russian probably explains that.
