You don't want to glue it on. The FRP expands and contracts a lot and it will bow and buckle. The plastic rivets are sufficient, and you want to drill the hole in the FRP a bit bigger to allow for movement.
I am redoing a 6 bay SS and have concrete walls to work with. What are the recommendations for FRP vs. Extrutech vs. Nuform panels? Any thoughts? Anyone ever use multiple types and have good/bad for each? Thanks

+1 on nylon rivets
+1 on getting them from Fastenal...or Farmtek
Leave a little room in between sheets for expansion as well. Your h-trim will cover this.
I went with Extrutech when I remodeled my tunnel 4 years ago. I replaced the FRP that was there before. The Extrutech is far easier to keep clean. The shiny smooth surface looks good even after repeated cleanings with harsh wall cleaners. It was easy to install and I think it gives a better look than FRP.
Rather than the plastic rivets from the FRP manufacturer, I buy nylon rivets from Fastenal Inc. The plastic rivets have a tendency to break and the nylon will not, also you can get the nylon rivets in several different lengths.
I'd use the ones with the metal pin.
As a rule, no, but I have seen washes where the water is more aggressive and will cause galvanized and plated metals to rust. I don't like the plastic pins because they have a tendency to bend instead of drive in properly.
