Just thought I'd add my two-pennyworth.

I use Percona MySQL. My first exposure to it came during my final job
(before I retired) - I managed a number of large and critical databases
running under Percona 5.6 - eventually upgrading to 8.0 (which was the
next release after 5.7) - and I also started using it at home. Percona
was initiated by several extremely experienced MySQL developers, and
they apparently made a number of improvements to the base MySQL,
including introducing several new configuration options, and the
innotop tool, which I always found invaluable for monitoring MySQL
performance. MySQL is a difficult beast to manage when running big
databases - it always seems to have a tendency to eat all available
memory, however carefully the memory usage is configured. (I haven't
as yet tried MariaDB, and I don't know if this aspect of it has been
improved.)
