If it helps, Bitwarden, including server, is open source. Of course that isn't a panacea by any means, but you can at least build it yourself and glance over the code. For me I prefer it to closed source for sure, and honestly even if the UI isn’t as pretty Bitwarden checks all of my boxes and tends to work really well across the platforms I use it on, including Linux, and it doesn’t have the same extension security troubles as many other password managers have had (1password prior to 1password X suffered due to communication with a desktop app and the complications that brings. Lastpass doesn’t do that, but has had arbitrary code execution vulnerabilities in their extension.)

And of course, Keepass XC is always a very formidable password manager.
