> There are services which allow you to upload via CLI and download via web browser, but they host your file so you have to wait for the full upload to finish before sharing the link.

There are exceptions to this; I've been making copyparty[1], an httpd which lets you start downloading a file that is still being uploaded[2]. If you catch up with the uploader, it'll throttle the speed so the browser doesn't drop the connection. Uploads and downloads can be done through browser and/or cli.

I recall there was at least one other alternative with similar functionality somewhere on the awesome-selfhosted list, but I'm failing to find them right now... It was prominently mentioned in the project's readme, but maybe that's no longer the case.
