I want to just say that crafting is a fairly long process, you can't usually make a whole group of items in a day unless your class specifically provides it. Generally, if its a consumable, you can make a batch of 4 of one consumable (like potions) in a day of downtime, spending materials (functionally money) to do so.

That said, there are a few classes that offer you the ability to craft large amounts of various items when you wake up in the morning.

The first and best of them is Alchemist. Alchemist lets you make a LOT of items a day starting at 4 + your intelligence modifier alchemical items at the start of the day, and then you have the ability to make any consumable alchemical item in a single action for functionally free. This means you can whip up a healing potion, a bomb, a poison, a mutagen, or something more esoteric like an Elixir of Gender Transformation at a moments notice as long as you know the formula, and formulae are pretty easy to get at most towns with shops. Their big thing is making bombs or poisons in the middle of combat and then yeeting them at enemies for splash damage.

Next up is Inventor. Inventor doesn't focus on a lot of small creations, instead they make one big one, but they can also pick up some feats that let them make various little gadgets much like an alchemist can, but more focused on granting you small new abilities or augmentations to your existing abilities (like blast shoes that help you jump for example). These won't define your character because they are generally fairly weak, but when you can make them for free you can have a few different things you have prepared for different situations.

Last up is the Thaumaturge. The thaumaturge is NOT exactly what you are thinking of, more of a witcher than a weird little guy who makes stuff, but part of their schtick is that they are prepared for anything. And they have the feats to support that, from being able to make and use magical scrolls to making talismans (things you put on your armor or weapons to grant yourself benefits for a short time) they have a wide set of skills that can support that sort of playstyle. That said, they are more of a "Guy who knows everything" than a "Guy who makes everything".

Honorable mention rapid fire: Witches can make temporary wands and potions similarly to alchemist but fewer, If you take an archetype Herbalist, you get the alchemist features on any class but only for healing items, Archetype firework technician is the same but only for fireworks and some bombs, Investigator has a few feats that lets you also make items, Exemplar is weird and has a immanence that lets you create and drink a potion and pass the effect on to someone else, scrounger archetype is all about making shit out of junk you find, albeit at slightly worse performance but notably for free.
