Add a keybind that:

• Open the Accessories inventory if in survival.
• Open the Classic/Creative inventory if in creative.

Because, in Creative, we generally need to open the creative inventory:

And we access the player gear using the Chest icon:

And we do not really need to access to Accessories inventory.

But, in survival, I would prefer to always use Accessories experimental inventory + small craft grid instead of the default one. I mean that I will not use the default inventory in survival anymore if I had this key.

The problem, is that I don't want to re-bind my inventory key each time I change my gamemode so I would like a keybind that open a different inventory depending the gamemode.

What is the use-case for an adaptive keybind? You can already explicitly open the Accessory view using the existing keybind (H by default) , and the normal inventory as normal.
