Unfortunaly, the latest macOS versions make it even harder to run 
software made by people that don't pay Apple 80 euro per year.

Their are two options:

Terminal
1) open Terminal
2) type: "xattr -d -r " (without the quotes, but with the trailing 
space; don't press return)
3) drag fpc-3.2.2-intelarm64-macosx.mpkg from the Finder to the Terminal 
window
4) press return
5) (possibly allow Terminal to access files in the folder containing 
that file)
6) open fpc-3.2.2-intelarm64-macosx.mpkg from the Finder

System Preferences
1) after getting the message about the system not being able to check 
the file for malware, open System Preferences, go to "Privacy and 
Security", and scroll down until you see a message saying that the 
system prevented you from opening that file. Click on the button to open 
it anyway
2) in the subsequent dialog box about it being unable to scan the file 
for malware, there will now be an additional "open" button
3) you'll get another, similar message afterwards when the package tries 
to run a script to detect whether the Xcode Command Line tools are 
installed. It failing to run will not block the rest of the installation 
though

Note that installing FPC will not result in anything appearing in the 
Applications folder. It only consists of command line tools. If you want 
a GUI interface to FPC, have a look at https://www.lazarus-ide.org/
