F# runs on .Net Core, which in turn runs near perfectly on Linux (incl Alpine). The runtime is about 50MB these days, so coupled with alpine or a minimal ubuntu server, you can squeeze a lot out of .net. F# is slightly slower than C# in some ways but in most cases you won't notice it and it brings a lot more to the table. I honestly wish most C# devs would start using F# for everything by default except the GUI layer, which C# makes more sense. If you are doing purely api/backend stuff, F# can be sharp knife you are looking for on linux.
