Forums are not as popular as before, although they remain popular for torrent trackers and joint purchase sites, technical support. Here is such a simple but ready-made forum can be done on Drupal 8 in 5 minutes

The order of the forums we can change with the help of crosses, by simple drag and drop. As a result, we will have such a forum:

On the forum settings page, you can set the number of Topics per page, Hot discussion threshold (topics with a large number of comments will be shown in a special block that can be displayed in the block settings). You can also set how comments will be displayed first new or old first.
Forum permissions settings
Drupal allows you to flexibly configure access to various functionalities. It is best to leave the ability to create forum topics only to registered users, so that it is more difficult for spammers to leave their spam messages. Answers on the forum are also best made available to registered users. But I think you can leave the viewing to everyone.
The forum provides us with several blocks:
Active forum topics are topics in which there are many posts.
New forum topics show new discussions.
