Using a vintage bike would be fun. I am partial to Cannondale touring models, but there’s lots of good manufacturers to choose from. Older Miyata 600/610s are quite nice, too. Brand isn’t nearly as important as proper fit. The touring frames are rugged enough for what you’re planning, and make for a comfortable ride. Make sure the frame has cantilever brakes for bigger tire clearance. On my older cannondale touring bike I have sidepull brakes that limit the tire width to 32mm. Fine for gravel, but I wouldn’t take it offroad. I also like either continental touring ride (knobby with a smooth center) for mix of gravel and road, or continental gatorskins if solely on asphalt. Wheels depend on your weight and load, but i have 36 spoke front and 40 in back. I’m also 220 lbs. Good luck.
