The app Gaia GPS has MVUM (motor vehicle use maps by the US forest service) that are outstanding. You can use multiple map layers at once. You can use the Caltopo plus the MVUM to see which areas are open and passable.
The MVUM are great but I've found that there are still many county and locally maintained but non-private roads, which aren't in the federal USFS/BLM MVUM and make it a bit annoying to figure out whats actually open.
