Error while setting value 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION' to 'sql_mode' about dbngin

Ended up solving my own problem.

I went into the downloaded binaries folder the DBngin downloads and creates, and saw that there was a my_print_defaults executable there. I ran it, and even though it errored out, it did say this:

Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/local/mysql/etc/my.cnf ~/.my.cnf

On a whim, I checked if any of those files existed and the first one (/etc/my.cnf) actually did, I assume from a previous install of MySQL that I had created and subsequently removed. After opening it, I saw this:

[mysqld]
sql_mode = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

I deleted the file, recreated the engine in DBngin and it started up perfectly fine.
