I don't know what the python-crypto list is for, but I'd guess it's either
for PyCrypto or a general interest python crypto list.
cryptography-dev is specifically for the PyCA family or libraries.

In general, using the output of a KDF as the key for symmetric
encryption is fine.

Scrypt salts can safely be stored with derived hashes in plaintext.

There's a request for KMAC,
https://github.com/pyca/cryptography/issues/12141. Thus far no work
has happened on it. If you're interested in contributing, we're happy
to review a PR.

It's impossible to say without seeing your code. If
encrypt()/decrypt() isn't working, then some of your parameters don't
match between them.

Based on "it creates a new key from the password and is used for
decryption" it sounds like you're using different keys for encryption
and decryption.
You need to use the same key to decrypt a value as you used to encrypt
it -- this is the point of symmetric encryption! It wouldn't make much
sense
It's correct that nonces do not need to be secret.

Unfortunately I'm unable to reproduce. The signature you provided
verifies fine with that private key.

You can pass any bytes value to the constructor:
https://cryptography.io/en/latest/x509/reference/#cryptography.x509.SubjectKeyIdentifier
(Sphinx doesn't highlight it, but you can see the constructor's
signature `SubjectKeyIdentifier(digest)`).
