So I was working on the mini yesterday and the brake pedal got pressed whilst the caliper was off.
Pads pushed in a bit so I had to push them back out to get the caliper back on the disc.
Now I've got fluid leaking. I think from the piston.
What's my best route and what is the likely damage?

You may have got a bit of dirt in or damaged the seals because the pistons extended further than they usually do. It will probably require a strip down and at very least clean but maybe new seals

Clean it up and be sure it is still leaking. Pushing the piston out isn't likely to cause damage, especially if the dust seal is still in place. But, there is a decent space between the two seals to fill, which will take time to drain. Bleed the caliper, then chock down the brake pedal to see that it holds sustained pressure.
