    I'm using PHP 7.0 from RC1 up until now RC4 without any problem.
    But the only 3rd party module I tested and use for more than a month is memcached.

    yes centmin mod centmin.sh menu option 22 doesn't work with PHP 7 as wp-cli isn't PHP7 compatible, so if you want to use centmin.sh menu option 22, run it on PHP 5.6 first and after wp setup then update to PHP 7 and be sure to disable auto update wp cronjob that centmin.sh menu option 22 creates as WP-CLI doesn't work in cronjob for PHP 7

    for WP redis caching, there's 3 (4th optional) steps
    1. install redis server
    2. install redis object cache wp plugin
    3. setup nginx level redis full page caching
    4. optional step setup PHP session storage via redis
    but step 2 and 4 don't work with PHP 7
    try a test site so you can test if the plugins you use with wordpress work on php 7
