The only ones I know involve the protagonist going to a post-apocalyptic future, like 7 Seeds or in a sense Dr.Stone, or from the past to our present like Thermae Romae. I don’t think there’s any real series from the present to a Cyberpunk/Sci-Fi future, the only one I know of is a hentai (I heard the plot is actually decent, but it’s still porn in the end).
I’m actually surprised there aren’t Isekai where the protagonist gets send into another in the future
What about an Isekai that gets thrown into our world from a fantasy one
The Devil is a Part Timer does that.
There’s a whole subgenre called “reverse isekai” that does exactly that.
