I had decent luck with Nuitka[1] as long as the project is 100% python. The executables are large but have been mostly portable IME (some glib problems can arise though).
Largest project I compiled was only ~1000 lines but used external deps of pymysql, jinja2, ldap3 along with the stdlib's shutil, tempfile, pathlib, and the base os lib without issues. It takes ~30 minutes to compile on a decently powerful machine though (8650u and 32gb of ram). Most of this time was spent on pymysql and jinja2's compilation.
