I’m on the same version of 1password, probably for similar reasons.
In their iOS app, there’s an entry in Settings -> Security -> Allow Universal Clipboard which lets you opt-in to passwords through the clipboard. I suspect there’s something similar on macOS.
Yes, I use this app multiple times a day, each time with the added satisfaction of knowing I own the app and not a subscription. Even if my credit card expires I will still have access to my passwords.
