Yeah I’ve always meant to check out nomad and never had an opportunity.
Though as I recall, it makes heavy use of consul, which I have used in anger, and makes me a little weary (though that experience is likely very out of date).
It doesn't require Consul IIRC, but bunch of features does depend on it, like service discovery and related stuff. But Nomad is totally usable without Consul for simpler setups.
I've been using Nomad for years without Consul. Maybe if you complex networking requirements it is worth it, else don't really need it.
Nomad has gained basic service discovery and K/V store without Consul. However, health checking is extremely limited.
