I think it would actually be easier to wow people than people think. You'd just have to focus on older technology rather than completely modern stuff. If you know that steam engines are a thing, and even vaguely how they work, you can build the king a pump to get running water without having to run massive aqueducts, or a crane to build his massive projects, or any number of directly useful things. An understanding of basic germ theory could set you up to be the best doctor in the world. Or even just a bicycle would probably be quite useful to get around without a horse, and I'm sure anyone could make a rough mockup of a bike.

I think you underestimate what it takes to get modern plumbing water tight and easy to manage. Threading, clean threading, teflon, and easy to manage plastic pipes, have all been invented within the last 200 years. Mostly, the last 80.

and that's just the literal direct infrastructure within a house. Water towers are not simple. Underground pipes are not simple. Civil plumbing and waste management is not simple.

Yeah, even electricity is easy to explain. You just rotate a high quality magnet within a coil of thin high quality copper wire. Easy.

Problems are:

  • How do you make a high quality magnet?
  • How do you purify copper fine enough?
  • How do you make a spool of the copper wire?
  • How do you make the bearings for the shaft?

Copper is the easy part. Get it hot enough and you'll end up with high quality copper.. Sourcing the copper is much more difficult.

Finding magnets is somewhat simple, you just need some iron... That's a lot more difficult. Iron smelting is way harder than copper smelting (especially without electricity).

Making bearings is also difficult. It requires not only iron smelting but also high precision machining.
