Which SQL mode values to use for WordPress?

I have a WordPress site running on a DO droplet and WordPress uses a localhost MySQL db. I want to migrate the db to a DO managed MySQL db. I have created the new db and completed migrating the db data, however, I have run into a problem… I found a warning in the DO documentation (the warning is in a red box near the bottom of page https://www.digitalocean.com/community/tutorials/how-to-install-wordpress-managed-database-ubuntu-18-04) that basically states WordPress will not work with a DO managed MySQL db unless changes are made to the global SQL mode setting. Unfortunately, the warning does not state what changes are needed. It provides links to MySQL documentation that provides details about SQL modes, but the MySQL documentation says nothing about which SQL mode values are incompatible with WordPress.

So, my question is: What is a typical, safe set of values to use for a DO managed MySQL db’s global SQL mode setting to ensure it will work properly with WordPress?
