I've found the Nat Geo waterproof maps to be quite good. Between the "Trails Illustrated" fold-up maps and the "Topographic Trail Guides", the east coast is pretty well covered. https://www.natgeomaps.com/trail-maps https://www.natgeomaps.com/trail-maps I also use Gaia GPS as a planning tool.

With this, my NatGeo paper maps largely become backups.
