what would be a good choice of (700c) rim width if I would want to run 30mm or 32mm tyres on my randonneur bike?
Minimum 23mm overall width, and you could go up to 30mm. Typical choice, per EEI, would be Mavic Ax19, there's a choice of three 23-24mm wide rims at different price points. Rigida Grizzly also has a good rep as a touring rim too, especially the CSS ceramic version.
