Also, I would be grateful to be able to sell/trash some of the random unwanted items from the inventory, at some point just having all sorts of fishing acessories in my inventory, several stone pickaxes, an absurd amount of halloween candies, as well as a single piece of paper I had once accidentally bought scattered all around my inventory just became very hurtful to my OCD.

You finished the actual content of the game.
When you see the last large event, a screen appears that says "Prologue Finished" and it has two options, continue (you can't) or go back.
You finished everything, for now!
Also, in Chapter 1 there is a Guild Chest. You can store basically everything there.
But also, most items are sellable in Chapter 1.
