As a card-carrying librarian, I recommend using Zotero as a client with a WebDAV backend (I use Nextcloud).
If you’re studying or writing anything in which you need to cite your sources, Zotero is excellent and has integrations with many word processors. I’m pretty sure it can output your references as BibTeX if you’re in one of the disciplines that uses LaTeX.
