Should I Upgrade?

With Java 11 you're running on a actively maintained long term support (LTS) version - which is good. The currently planned end-of-life date for this version within the OpenJDK project is 2027-10.

However, you might consider upgrading to a newer LTS version Java 17 or Java 21 to get advantage of the latest features and improvements.

Also you may upgrade to the latest non-LTS release Java 24 if you want to stay ahead and are prepared to upgrade regularly.
