I don't know something weird that also involves giving your login and password to this cookie.

I don't think the password is necessary. According to the docs, that is an alternative authentication method. https://bitcoincoredocs.com/tor.html. It is either Cookie Authentication or Hashed ControlPassword.

Edit: Upon further research, I was confusing Tor Browser, with Tor. I have Tor Browser installed, but not Tor, so I guess I could follow that tutorial to install it. I thought Tor Browser included the Tor service which you could run separately but you need to install it yourself. I still need a proper tutorial tho.

Good, you've figured out your first mistake. That's why it is called Browser! It is a standalone project that uses TOR and is different from the global tor service. Which Linux version are you using?

Last time I did this for my servers I used something like this, check it out: https://ubuntuhandbook.org/index.php/2021/01/install-tor-tor-browser-ubuntu-20-10-20-04/. It should be pretty straightforward. Let me know if you manage to do it.

proxy=127.0.0.1:9050
listen=1
listenonion=1

But some use the tor service, and have to register some sort of cookie

There are two difference here:

1) TOR more as a "client" with a lower level of integration, which would be connecting through the proxy as you have written above. This method does not have any authentication.
2) Authenticated mode with access to the Tor control protocol, deeper integration with the service. This is where the cookie authentication would come into play.

I am not sure if I remember correctly, but in the first method you would not get a .onion address and in the second you would. You can check the debug log for information about this. I am no longer 100% confident, but I think that in the first case the node would not act as a full peer despite listen=1 but I must freshen up my knowledge about it. Perhaps someone else can confirm.

Did you read the Wiki entry? https://en.bitcoin.it/wiki/Setting_up_a_Tor_hidden_service
