Evergreen Safety Council holds the MSF ERC course over the winter months down in Renton (but they call it the Intermediate Rider Course). This course might be perfect for you. I haven’t taken it yet so I cannot comment on what level it is. WebBikeWorld complained this MSF class was like a compressed Basic class so that might be exactly what you are looking for? The next class is January 19th.

I’m pretty sure there is a track place nearby that teaches you how to handle your bike (not how to race). Cannot remember the name of it off hand. Don’t know if they do any courses over the winter months though. Once I get a bit more experience myself I plan on taking that course. Only got a few thousand miles under my belt just now.
