The Protheans from Mass Effect are a famous elder race. They were highly advanced and had a great galactic civilization before they were wiped out. Their technology and knowledge were left behind and were crucial for other races to discover and study. Then there are the Goa'uld from Stargate as well. They are an ancient and powerful race that has a complex history and a lot of interaction with humans in the Stargate universe.
One common theme is the advanced knowledge and technology of the elder races. For example, in many stories, they possess the ability to travel through space in ways that are far beyond human capabilities. Another theme is the relationship between the elder races and younger species like humans. Sometimes they act as mentors, guiding the development of the younger race, while in other cases they might be seen as a threat, perhaps because of their different values or the fear that they might overtake or dominate the younger species.

Well, it's a bit of a gray area. While Elder Scrolls is often thought of as a fantasy series, it does have some elements that touch on science fiction. For example, the Dwemer were a race with highly advanced technology that bordered on the fantastical but could also be seen as a form of science fiction technology. The way they manipulated the world around them with their devices and constructs is not too far off from what we might expect in a science - fiction universe.
Well, from the 'list of alien races in science fiction', the Martians are quite well - known, especially from H.G. Wells' 'The War of the Worlds'.
