More advice. I have no idea what level talent is in the area where you and your son live. But here on the west coast and likely Nashville where there are some very serious talent volunteering their time for non profit work or for causes Reaching out and offering to be available in some capacity for these events (preferably on stage or helping out) could give him some nice connections and an opportunity to play with talent that he might otherwise not have the opportunity.

They may also make some recommendations to him venues, bands, etc networking wise. Also if he reads music and can play off lead sheets and it truly good, have him stop in at the local recording studios and let them know he's available. They'll have other players for sure but it never hurts to start talking to the locals making music in the studio. Maybe he can even do some interning hours. Good place to also learn and network. As mentioned most musicians put it together doing a variety of work and in a variety of venues.

Definitely learning singing and about harmonizing would be fantastic. Singing and harmonizing will serve him well in the long run in a variety of ways.
