>since there's no more resistance there than in the other direction?
But there is.
Suppose it tries to expand inwards. Then the material on the inner radius will have to force itself into the smaller radius of the hole - but since it'll be going from all directions, it'll have to compress against itself to fit. That's where your resistance comes in.

When metal gets heated it expands and contracts when it’s cooled.

The path of least resistance is more like circumventing an obstruction. Continuing the path of resistance is going to increase work or energy.

For example if your walking and you see a wall you will take the path of least resistance which is going around that wall

Why would you use more energy and time climbing that wall?

Water will do the same thing.

If you have a cup of water and pour it out on the ground and watch the water flow. Now obstruct that flow with a brick and the water will go around the brick.

Electricity works similarly it will take the shortest path that completes a circuit. Which is why having a short in a wire can be problematic. It can touch metal and shock you or cause equipment to malfunction etc.

Metal does not swell like foam when heated, rather it expands isotropically. Every material point along the perimeter of the hole expands in the tangential direction also, and thus the circumference of the hole must increase
