I'd lean towards spacing out proficiencies so that you need more more than a 1 level dip to get All Armors, All weapons.
If 1-2 is an Apprentice tier I could see limiting the profieciencies you get based on what you'd be exposed to: a handful of weapons and only armors that cost 100gp or less.
Fighter 1:
Weapon proficiency: Choose 3
Armor: Light, Medium, Ring and Chain, shields
Fighter 3: your training is complete Jedi
Weapons: all
Armor: all
Same for the other classes that pass out more proficiencies than you can use at Level 1.
Although I'd get rid of the double penalty for Nonprof - no bonus, and disadvantage.
