Solr will work perfectly if you want to do a standard search (db, shop) or need a customized approach, like custom transformers, ranking, etc. However, if you aim for "something that just works good enough" and has much better scaling capability and tooling, you can't beat ES/OpenSearch here (Solr scaling is much more manual process than ES/OS). And if you want to stay away from ElasticSearch drama, stick to OpenSearch - they are shipping excellent stuff these days.
