You're best bet may be to look for each state individually, or at least regionally.
The RAMONA GIS inventory, a NSGIC project, lists data layers and associated metadata for all 50 states. Information is voluntarily provided, so some states have more info. than others. Data cannot be downloaded from RAMONA, but the brief and detailed metadata will include download address, ordering info, and/or contact info.
Furthermore, The NSGIC website has a list of GIS contacts for all 50 states. The contacts tend to be managers/leaders, so they may be able to point you to appropriate resources for their state.
This approach will most likely lead to datasets in several different resolutions/scales. However, I think it is your best approach if you're looking for larger scale data.
