The avionics bay is for maintenance, pilots don't get to touch any of it ever.

And pilot training covers the systems not in a physical sense but in a logical "power is supplied to this system via the secondary avionics bus which is fed via this breaker from the generator on the left engine or via another breaker from the main avionics bus" so you can debug and understand what it means when some bus fails or you loose a generator. But we really don't know where the actual wire is or even whether the schematic we learn about different buses is really wired that way or only behaves that way.

Just seems weird to brit have had just a basic tour of every part of the plane so if smoke starts pouring out of the hatch they know what it looks like down there.

It is part of type rating training to learn on paper (well, usually ipad/computer based training) what is where on the aircraft. But that doesn't mean pilots ever really go there in the real plane.

sure there’s no reason To go in normal cases, but I’d think a pilot should know every inch of the plane. I’d expect a captain of a ship to have been in the galley for example even if they normally don’t need to go.
