Practical
Scale, the small airport, and the spring river
Quiet is the practical feature, and it has a cost in choice. Fewer late options than Moncton or Halifax is normal, not a failure you should try to fix by picking a louder brand. Downtown covers the river and the legislature of the province. The hill covers the university. If you are visiting someone at the university, the hill may be worth it. If you are visiting the capital, the flat centre is usually enough.
YFC is west of downtown, a small airport and a short drive in ordinary weather. Do not expect Moncton's flight list. If your route is easier through YQM, sleep in the hub and drive to Fredericton in daylight rather than forcing a connection that does not exist. Spring high water is the other planning item. Ask about river trails if your week depends on them. The downtown streets themselves are rarely the flood.
