More Insight? I already gave you the secret antidote. What more do you want?
Screw the pocket knives - you need to figure out which flavor and brand of kimchi you can stomach. There's another side of kimchi besides its antiviral properties - it's a repellent. The more you eat, the farther away from you non-eaters will stay.

Anyway, your original question was flawed. If "everyone" is confined to their homes, by definition there will be no "best jobs". Everyone will be at home, not working.

However, to placate you, I will offer the obvious "easy" answers:

Good Jobs:
Hermit
Rural Farmer
Lighthouse Operator
Eskimo
POTUS (or other government officials high enough in status to be a bunker dweller)

Bad Jobs:

Doctor
Nurse
Cop
Teacher
Family member of a teacher
Any other job in a school.
