Thick landscape fabric underneath the liner, then the liner, then another layer on top of the fabric. This will help protect the liner during and after construction.
Line your pond with rocks. Some people on this sub say you shouldn't, but I don't agree with that. It looks better, Safer to walk on during cleanings, and is healthier for the pond (nitrogen cycle and all that).
Also think about it....where in the entire world is a naturally occurring body of water that has zero rocks in it? What natural body of water is completely smooth? Nowhere that's where.
I also am a big fan of the natural looking ponds/waterfalls. you want to make the feature look like it was there before you even bought the property. This means using local rocks and working with the current landscape you have (no volcano building).

The more rocks and gravel you have, the more surface area you have for beneficial bacteria. I never use smaller than 3/4 inch gravel. And the largest rocks I can get my hands on.

I would never have a pond without rocks, but they are more work. Also, if you have fish they can get trapped. We found one of my wife’s precious giant gold fish trapped. I was sure it was dead but it sprang to life after freeing it. Now we take a quick census for trapped fish every once in a while!
