I doubt the lack of UDS, and having to use FCGI over TCP/IP is what is
causing your load spikes compared to running with mod_php.

More likely you need to tune the PHP-FPM side to start (+limit) the
appropriate number of processes appropriate for your workload and
available resources. A common cause of poor req/s is trying to service
too many requests simultaneously, ie starting 100 FCGI workers on a 2
CPU server.
