Strongbox TRIAL RUN!! I exported the couple hundred entries from my 1Password and imported them to the Strongbox app that I downloaded from the Mac App Store. Now I’m in position to run both apps side by side until I am confident of Strongbox and willing to accept its differences and limitations. Or my standalone license for 1Password7 stops working. 
The export and import was picky. Spent a lot of time in the Numbers app looking at the CSV file for problems. Had to edit some fields in 1Password to get them to export right. And I had to tweak the CSV file itself before it would load okay. Seemed to be picky about number of columns and even “Url” but not “URL” for column header? I think.
Experienced a crash and loss of items due to badly formatted input data. Once I had the CSV file cleaned up well enough, it stopped doing that. (And of course nothing I’m doing in Strongbox affects the data in 1Password, so I’m free to experiment all I want.)
Strongbox is a nice simple little Mac app compared to 1Password. It won’t be for everyone. But it is a native Mac app, it does allow me to keep my data on my Mac, and it is even available for the non-subscription price of $23, which I have paid.
On import, it really only handled five fields: Title, Username, Password, Url, Notes (and also claimed an Email field but I had no such data). My credit card and other non-password records imported mostly empty of data.
Strongbox is probably not for you if you need family or company sharing. Sharing among devices is supposed to be possible any number of different ways. My next step will be to figure out the best way to get my Strongbox data from my Mac to my iPhone.
