Mine isn't from those email hosts, but it from google cloud or Azure typically (not AWS for whatever reason). Related, the gmail spam filter is terrible.

It seems insane that gmail doesnt provide a way to automatically send a mail (eg based on domain, keywords, etc) to spam. I know theres block sender but for example aliexpress uses a different name for every email so that's useless.
Most of my spam is from gmail addresses. Why Google hasn't figured out how to stop the fake Norton renewal notices is just mind-boggling.
Lately I've also been getting a lot from compromised MS365 accounts.
