I don't think most of the posts are what this thread was actually about. I think it went off the rails relatively quickly into a debate about rules regarding martials (or arguably fighters). But I think the OP was asking a roleplaying or build question not a rules question.
You can broadly break non-casters into two groups by subclass:
Supernatural non-casters:
All Monks, Echo Knight, Rune Knight, Eldritch Knight (technically a caster), Psi Warrior, Arcane Archer, Ancestral Guardian, Wild Magic, Storm Herald, Beast, Arcane Trickster (technically a caster), Soulknife, Phantom
Mundane non-casters:
Battlemaster, Champion, Purple Dragon, Cavalier, Samaurai, Totem, Battlerager, Zealot, Berserker, Assassin, Inquisitive, Mastermind, Scout, Thief, Swashbuckler
In terms of power the Supernatural non-casters are generally superior to the Mundane non-casters of the same class.
