Points of interest and amenities are probably the next most useful. Things like street lighting and sidewalks quite helpful for pedestrians. It's more important that you are still enjoying mapping. If there is something that you know is useful but you find tedious it's ok to skip it and either leave it for someone else or come back to it later
As it sounds like you're on Android, I'd recommend @streetcomplete for easily adding detail while on the go.
