I would say the Jungfrau region is best as it's a larger area with things to do at lower and higher altitudes. In Zermatt, everything is at higher altitudes and in May things could be muddy as the snow is still melting away. Lucerne will certainly be fine as well in May. City center or countryside is a personal preference, either is fine. A nearby train station is a great benefit. Both Meggen and Lucerne have a train station. Lucerne is more central so you may save on traveling time.
The risk of fog near large lakes doesn't ring a bell to me. There can be fog year round, but the fall is more risky than another other season, particularly at low altitudes. The lake areas often get more hours of sun than mountain resorts in my experience.
