Data directory path mention in cnf is of old mysql. Make a fresh data directory, configure it in configuration file and execute mysqlinstall_db, I don't understand the sentence about the data directory path mention. The my.cnf file is at /etc/my.cnf . It doesn't have any data directory path mention, but neither does the my.cnf file on a laptop, which works. So there seems to be nothing wrong with the location or content of the my.cnf file.
your current problem is that you have no clue where your mysql-datadir is *because* it's some random default, from the moment on you specify it
a) you know it - good for a million reasons b) it is empty and you can start from scratch or you seek the current one and make the folder empty and start withmysql_install_db initializes the MySQL data directory and creates the system tables that it contains, if they do not exist.

I cannot run the mysql command because it challenges me for a password. But I did not set any password, either for the root, for mysql, or for myself as a user. So the installation has somehow installed passwords about which I know nothing or there is some error in the installation process. There is a lot on the Web about resetting a forgotten password. But the assumption is always that you can get at the program via some other password. But in this case every door is shut. Does anybody recognize this problem? I've uninstalled and re-installed the program, but the results are always the same.
