My answer may not be applicable to your question. I'm a reader of novels. My goal is to help people solve problems, not to write novels. If you have any other questions, I'll be happy to answer them.
One of the best stories is Tressa's. Her journey as a merchant, exploring different towns and encountering various economic situations, is really engaging. It shows her growth from a novice merchant to a more experienced one.
One interesting time traveller story is 'The Time Machine' by H.G. Wells. In it, the protagonist travels to the far future and witnesses the evolution of humanity into two distinct species. Another is about a person who claims to have travelled back in time to see dinosaurs. There are also stories of time travellers trying to change historical events but often facing unforeseen consequences.

There's also the story of a time traveller who visits different eras just to experience the culture and architecture of those times.
Well, 'The Time Machine' by H.G. Wells is a classic time traveller novel. It's about a scientist who builds a machine that can travel through time and his adventures in the future. Then there's 'Doomsday Book' by Connie Willis. It involves time travel to the Middle Ages. Also, 'Kindred' by Octavia Butler, which has a unique take on time travel as the protagonist is pulled back in time to the antebellum South in the United States.
One popular Japanese time traveller story is about a young girl who finds an old pocket watch. When she touches it, she is suddenly transported back to the Edo period. She has to adapt to the different customs and language. She meets a kind samurai who helps her survive in that era. Eventually, through some mysterious power related to the watch, she manages to return to her own time.
I recommend "I Tortured the Male Lead to Ashes" and "The Master of the Male Lead Dressed as a Black Lotus". They were respectively a mystery detective-Netherworld Love and a Xianxia Tale-Classic Xianxia. The male lead was tortured very badly. I hope you like this fairy's recommendation. Muah ~😗
One popular trope could be the 'lost in space' scenario. The traveller finds themselves in an uncharted part of the universe and has to figure out how to survive and get back. Another might be the 'alien encounter' where they meet a new and strange alien species and have to communicate and co - exist. And there's also the 'tech malfunction' trope where something on their ship goes wrong and they have to use their wits to fix it.
The main elements are the act of time travel itself and the contradictions it creates. For example, changing the past which then affects the future in a way that seems to defy logic.
