Party Command Hooks MV + MZ

(This is a quality of life plugin for devs. While the player-visible effect can be created also with Events by creating all message variants manually, it will hopefully save you a few hours of tedium.)

Party Command Hooks lets you observe data like (intended and effective) change amounts, Icons, Names, Descriptions (and more) from Commands in the “Party” category to control Switches, Variables or text snippets shown to the player.
This means it can be used to, quite easily, set up nicely formatted messages that let the players know what exactly they just found in that broken crate in the second basement, and how to use it, all without item-specific Event logic.

It also supports language-agnostic joiner escapes to help with a/an and plurals.
Additionally, you can easily define any number of custom Note Tags per hooked Command to control additional Switches, Variables and Text snippets. This is especially useful if your game is not in English and requires gendered articles, classifiers and/or counters that vary between individual items.
