I would recommend SQLite + a nice usable interface tool like

datasette

https://github.com/simonw/datasette

Or SQLitebrowser https://sqlitebrowser.org/

(There are other generalized tools, search around to see if there are more suitable.)

You can store whole files, in addition to searchable text fields , and the single file is easier to share or turn into a more sophisticated “app” when the time is right.
