The RHEL/CentOS out-of-the-box apache tls is a little old but operational. This Mozilla resource is excellent for getting apache tls config up-to-date.
I'm not 100% on any differences in ciphers available, but I don't think there should be much difference between EL7 and Fedora.
This config gets my an A+ rating on the sslabs test:
SSLEngine on SSLProtocol all -SSLv2 -SSLv3 SSLCipherSuite "EECDH+aRSA+AESGCM EECDH+aRSA+SHA384 EECDH+aRSA+SHA256 EECDH+aRSA+RC4 EECDH EDH+aRSA !aNULL !eNULL !LOW !MEDIUM !SEED !3DES !CAMELLIA !MD5 !EXP !PSK !SRP !DSS !RC4"

IIRC the Red Hat defaults are somewhat conservative on their limitations in order to simplify and maximise client connectivity - as some stuff (especially java apps or older mobile devices) tend to struggle otherwise with only a strict set of secure ciphers.
Outside of Qualys, I found the following sites interesting :
