Ever since Oracle changed the licensing of Java in 2019, there has been a lot of confusion in the market. Found the below blog article to be extremely useful in this regard -

As of today, the best bet for developers looking for LTS (Long Term Support) is to use Eclipse Temurin. Memebers of this consortium include IBM/Red Hat, Microsoft, Azul, New Relic, Alibaba, T-systems, etc. A list of all OpenJDK builds by Temurin is available here https://adoptium.net/temurin/releases/
Other option for LTS is Amazon Corretto: https://aws.amazon.com/corretto/?filtered-posts.sort-by=item.additionalFields.createdDate&filtered-posts.sort-order=desc. Amazon provides LTS at no extra cost. Similary Microsoft, Red Hat also provide their LTS bundles of OpenJDK.
It is important to note that OpenJDK available at https://jdk.java.net/23/ (openjdk.org) does not have LTS. OpenJDK.org site is managed by Oracle primarily and Oracle provides TLS only if you purchase the license of Oracle Java SDK (not OpenJDK).
So, if you are just using the latest download from Openjdk site, then as soon as a new version is available, the older versions are NOT patched! So you will not get security patches for older versions and this can be a concern for production environments.
OpenJDK builds having LTS are typically supported with patches for 4 years...so you have time to plan your upgrades. Security is a major concern in software development. LTS versions receive regular security updates, ensuring that vulnerabilities are patched in a timely manner. Another good blog showcasing the various LTS options is here - https://www.petefreitag.com/blog/java-lts-versions/ and https://adoptium.net/support/
