Although few answers, think SQlite seems the best option.
For use I prefer HeidiSQL Portable (OSS
https://www.heidisql.com/download.php ) where I don't need to install in Windows. Just download, unzip and run HeidiSQL.exe then can create a new database file and create database and tables, or easier, use the export to database function to copy it from/to MySQL or other large SQL DB in a breeze without worries about charset support, fields mapping etc like in CSV that demand a lot of time.
Just tried the following in 15 seconds (sample 1k data from known leak in this forum):

The DB's I may share in future here in the forum, for sure in SQLite.
