Aurican's Lair's "The Great Big Random d100 Table of Interesting NPC's (5e)" isn't exactly random, and can be used for more than D&D. The free supplement is a table of 100 NPCs. Each NPC has the expected description and stats, but also a relevant plot hook and carried equipment, as well as a link to a picture of the NPC. (I haven't checked if all the pictures work.) Entries were made by individual redditors. Most of the NPCs are better in villages and urban environments, rather than as adventurers on the road.
