10.6 is LTS for another 2 years, so that gives you a bit of margin.

Regarding Docker, according to general literature (https://dev.mysql.com/blog-archive/mysql-with-docker-performance-characteristics/), MySQL/MariaDB tends to perform well with the right setup, although as in any case I would encourage you to run your own benchmarks.
I do myself run an instance in a production cluster on bare metal with Debian 10 without any performance issues.

Yes I am aware that support was discontinued and that its far from ideal but getting the OS of our 3 node cluster upgraded is a project that our infrastructure team is still planning.
So as DBA I am just trying to come up with alternatives in case we encounter a serious issue that would require a MariaDB 10.6.x upgrade.
