If you are willing to stretch what might be considered SciFi:
Tik-Tok of Oz by L. Frank Baum published in 1914.
"Very well," said the Wizard, and without any fuss or mystery whatever he performed a magical rite that was simple and effective. Therefore those seated in the Nome King's cavern were both startled and amazed when all the people of ...

Yes, a televised moon landing was predicted in one Golden Age story that I know of: "All Aboard for the Moon" (novel, 55000 words) by Harold M. Sherman in Amazing Stories, April 1947, available at the Internet Archive. Apparently never reprinted.
The following excerpt is part of Gil Benson's ("playboy; devil-with-the-women; and rich") speech just before ...
The earliest example I can find of a hand-held 2-way electronic communications device is Dick Tracy's 2-way wrist radio which appeared in the Dick Tracy comic strip on January 13, 1946.
There must be many earlier stories that involve communications by magical (or other non-scientific) means.

Looking through the list of Niven's works, the most likely possibility seems to be his letter/essay in Riverside Quarterly Vol 3 No 1, published August 1967. That's less than 2 years before the Apollo 11 landing, as you said, and still a few months before its crew was announced on 20 November 1967.
There are fairly few Niven works from the 1960s, and most ...

Some of the details don't jive (frex it's not a short story) but in part II of Asimov's Second Foundation Toban Darell has given his daughter Arcadia an automatic typewriter (called a "transcriber") as a birthday present. She is trying to use it to write an essay on Seldon's Plan.

The technology that keeps everyone indoors is portal transportation,

Credit for inventing the idea of a satellite (i.e., an artificial satellite in Earth orbit) goes not to Clarke but to Edward Everett Hale and his 1869 novelette "The Brick Moon" which is available, along with its 1870 sequel "Life in the Brick Moon", at Project Gutenberg.
