The most valuable parts of 1Password for me are storing non-password stuff like license keys, secure notes, random security question answers, and the like.
I’ve always used secure notes in the Keychain app for this. Not as smooth as 1Password, but it does the job when I need a licence number (when I get a new computer, so once every ~3 years) or an answer to a security question (can’t say how frequent that is; certainly not more than 1 every other year).
I’ve been doing that for more than a decade (more like 2 actually) without a hiccup.
