What you have on the highway tag (which I may move to a usage page) looks fine to me.
I couldn't give you an opinion on how to apply them to roads in California because I've never been in that state. I drove a truck for awhile in the US and there are quite a few roads that won't fit nicely into those categories. That's OK. Just make sure that the highway tag represents what the road looks like in general. Later you can add tags for number of lanes, size of shoulder, shoulder type, divider type, etc. I don't know how the rendering rules work exactly. I would like it to use the highway tag if other data is not available. I remember a state highway that looked like an Interstate except that it had turn lanes and stop signs for the traffic on the crossing roads. I think I would tag it as motorway even though it didn't have ramps.
