WeasyPrint works really well for me. It can support all of the languages and fonts I need. I run it on AWS Lambda and in Docker as a web service.

I previously used WKHTMLTOPDF, but it hasn't been supported for years and doesn't support the latest CSS, etc. It does support JS if you need it, but I'd probably look at headless Chromium or another solution for JS if needed.

This is my experience and recommendation too.
