I wanna reverse CGI binary file.
Is it possible?
What are the recommended tools and guides?
Thank you for reading my question.

$ file test.cgi
status.cgi: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.3, for GNU/Linux 2.6.16, stripped

You can use radare. It is a free framework.

$radare2 -aarm -b32 test.cgi

CGI is not a specific type of file; it more so describes the way the file is interacted with. A CGI file could be a script written in any scripting language (e.g. Python, Bash, Perl etc.), or it could be an ELF executable like you have here.

Since it's just a normal ELF, you can use any common disassembly/decompilation tool that you would use for other binaries.
