The usual go to for self hosted password managers is VaultWarden. There’s no deb or rpm package but you can get it spun up with docker pretty easily. Any reason you’re specifically looking for “included” or packaged solutions? That’s going to severely limit your options.
I use my laptop for anything that requires a real keyboard or bigger screen. Then I have my server, and my phone. So I mostly just use the laptop and the phone. I do have a dual screen phone though so that helps a bunch for multitasking.
