Fedora comes with manpages. So for instance, say you want to place http pages outside of /var/www. Fedora comes with the selinux-policy-doc package, which gives you the httpd_selinux manpage:

https://linux.die.net/man/8/httpd_selinux

It's a tad dense, but in the Sharing Files you can find a section explaining what context is used and for what. You can also look at the existing context, eg:

    $ ls -laZ /var/www
    total 4
    drwxr-xr-x.  4 root root system_u:object_r:httpd_sys_content_t:s0       33 mar 17 17:32 .
    drwxr-xr-x. 21 root root system_u:object_r:var_t:s0                   4096 abr 18 10:57 ..
    drwxr-xr-x.  2 root root system_u:object_r:httpd_sys_script_exec_t:s0    6 mar 17 17:32 cgi-bin
    drwxr-xr-x.  2 root root system_u:object_r:httpd_sys_content_t:s0        6 mar 17 17:32 html

And copy those for your own use.
