What other fonts other than "futura-demic-reg" do browsers support without a connection?

Question

css

I spied the font "futura-demic-reg" on one site, rummaged through everything and did not find that it was connected somewhere in css or inline.
Works in all modern browsers (did not look at the old ones).
I do not remember that it was one of the standard for the web.
If I'm not mistaken, helvetica neue can also work.
Tell me, what other fonts are there, where you can learn more about them.
PS: I apologize if the question is not correctly formulated.

Answer 1

Google "safe fonts"
Helvetica, by the way, is not. It is present only on poppies.
