I would look for a 90s steel hybrid and update the components and position according to budget / requirements
pros: cheap, available, quality frames (some), retro, recycle, some in pristine condition
cons: outdated specs (canti only, threaded fork), research needed to identify better frames, low spec components
Some to look for are: Bianchi Boardwalk, Specialized Crossroads, Trek Multitrack, Diamondback Overdrive, and Giant Innova.
If you want new, I would start at the wheels first because that would dictate your frame requirements and usually require something handspun if you want 135mm QR, disc, and narrow 700 rims.
