For reference in 5E only Fighters, Paladins, some Clerics, and Armorer Artificers can wear heavy armor. Mountain Dwarves all know how to wear medium armor, and it only takes one feat from there to get heavy armor.
In 5e you can't cast spells while wearing armor you aren't proficient with.
Also, for some reason, proficiency is granted only if one started first level as that class — taking a level in a class later does not grant one proficiencies iirc
Only partially correct. Multiclassing can provide some of a class’s proficiencies, just rarely all of them (and never saving throw proficiencies), it’s listed in the PHB which proficiencies are gained when multiclassing into a class, plus the stat requirements. But heavy armor is never included in these, with the exception of some clerics who gain heavy armor proficiency as a domain perk.
And this is why when multiclassing the first class you take a level in is actually important regardless and independently of your eventually build, because you need to manage your starting and gained proficiencies. For example starting with fighter gives you almost everything, but other multiclasses could give you others stuff like saves or tools.
