So my question is, would that be a password I chose or that Multibit assigned for me? If it's assigned then I think I'm screwed because I can't find anything saved anywhere... if I chose it myself I'll keep trying variations I've used over the years.
Definitely one you chose... MultiBit Classic, by default, creates wallets without a password. You have to explicitly add one to the wallet yourself.
If you have any experience with the command line and/or Python, you might find that btcrecover by gurnec (

You can also use hashcat to try to recover your password. In case you were lost with command line and rules in hashcat, we can provide assistance
