"Search engine 'elasticsearch8' is not an available search engine"
setup:install checks --search-engine against the engines the release has modules for (Magento\Setup\Model\SearchConfig) and stops before it connects to anything. Releases from before an engine's module refuse it, and releases that dropped an engine refuse it too.
