About the weapons management, i don't really see a problem. They're almost akin to ammunitions the way they're treated here. Let's say you find a nice weapon with 15 ammo in MGS V, you use it in an enemy camp and you finish all of them. What happens next? You search for more in enemies bodies and around the camps. What happens in Zelda? You have a weapon that gives you (for example) 15-20 hits, when it breaks you go around the world or in enemy camps and search for more, with the addition that you can also throw it before it breaks to deal 2x damage. With ammo you press a combination of keys to reload, in Zelda you use a button on your dpad to change the weapon you're using. The fact that each sword/spear/hammer/etc has its own moveset also adds a lot in terms of gameplay variety and strategies because you will be using the weapon with the most effective moveset for each enemy.
About the dungeons aesthetics i don't know what to expect, but if there's a reason in the lore for that theme to be recurring it's not going to be a problem for me (unless it's not pleasing).
