Does it make sense to have separate emails for each individual financial account (banking, credit cards) or is that overkill? I’m just thinking that if a hacker got access to one email they’d have all account information?

I do this for every website, not just financials. As long as you have a quick and easy way to create the email aliases and you’re using a password manager I think it can be an easy and effective boost to security.
I might actually recommend it for anything except financials. For some things, your email address is the only way to access or recover things on the account.
I want something very stable as my email address for such cases, because I don’t want to risk my email alias provider shutting down, or my self hosted setup to randomly die. Or even some weird “security measure” where the bank decides that any unknown domain is no longer ok.
You’ve used some phrasing that I am not really following. What exactly do you mean by “stable” in regards to an email address? And what is an “unknown” domain?
Although I agree with you, I don’t think that’s what OP was asking about based on this part:
It seems they are asking if an separate email account for each service would be beneficial. My opinion is it would limit the attack if an email account was hacked, but definitely not worth the hassle. Email aliasing (like the comment above me says) gives you some of the benefits without needing to juggle multiple accounts.
