I’ll get the ball rolling.
This year we discovered a brand called Jenolite that has some very useful products.
Stop Leak Sealer Spray: a ridiculously helpful and useful product that helped us patch an annoying leak on our garden room roof: https://amzn.to/3PieDft
Epoxy putty stick: this stuff worked a treat to seal a crack on our home sewage treatment plant aerator manifold. Simple to use and very effective. It’ll also seal any plumbing leaks on plastic pipes: https://amzn.to/3LgGhZ8
They also make a copper epoxy putty that we haven’t used, but based on their other products, I’m guessing it’s a winner too: https://amzn.to/3UvyLhs
Their pipe repair bandage also looks useful: https://amzn.to/3QYUbQT

Rather than a product, my top tip is to know how to turn your water off and make sure all the mechanisms work. That means the street stopcock, the one in the house (or more than one) and any individual isolators for taps, tanks, etc. It's hard to think straight when there's water everywhere! And everyone (within reason) in the house needs to know.
@kev-m Great point about the stop cocks. That is essential. When there's a leak, head straight over and turn off the water.
On that note our plumber that did some work for us as part of our utility room refurb, "found" a valve that was hidden behind the HW tank that isolated our hot water. Handy to know where all these things are.
As part of the refurb, we popped an Eve Water Guard under the washing machine to alert us if there was a leak from the washing machine.

I have found Compression Repair Couplings invaluable to have as part of an emergency repair kit or a pipe repair clamp although this is not permanent.
