HTML, css, js, (maybe jquery and font-awesome if I want to get fancy) and all static files dumped in an S3 bucket for as long as I can get away with it, then django if I need anything more. Not that I think python/django is the "best", but it is what I know and it's got all the batteries included out of the box. I've never made a sufficiently advanced UI that required react/vue/etc. So I still just stick with html/css/jquery on the front end.
Semi-related side note: I do use TS/react in my 9-5, but the more I use it professionally, the more I'm convinced there is no need for it outside of trying to get a job, IMO.
