wa-sqlite on top of OPFS is actually pretty great these days. Performance is about half of what I'd get in native SQLite, which is not too bad overall. It's around 10x faster than SQLite on top of IndexedDB for large databases in my experience.

It's much better than WebSQL could ever be. You get the full power of modern SQLite, with the version, compile options, additional extensions, all under your control.
