Can a network worm spread inside a home networking?

I've seen a lot of IT tales where a worm propagates itself by emailing itself in a company's network. Was the worm able to do this because in a company, people's emails are saved on everyone's computer so that they can communicate with each other, so the worm just took advantage of it? Is there such a thing as a worm scanning a LAN network for email, or scanning ports that are for emails and then send email through those ports, and somehow it will arrive on an email client(like Gmail app)? And my last question is, are there any other ways a virus can spread in a home network? I don't have any share file folder turned on in my LAN network so that should help. I'm asking this because I want to understand and improve my home's LAN network.

Yes, lots of malware and ransomware will attempt to use known exploits to spread wherever it can reach. Local network or internet. It entirely depends on how it's written.

In regards to your email example, it's usually an attachment that when opened uses another exploit chain to run it's payload (sometimes this is as simple as attaching hotnudes.avi.exe), whatever that may be.

Frequently for email propagated malware, it will use the address book of the compromised machine to spread which is likely to be lots of addresses in the same or connected organizations.
