Personally I use Enpass.
It’s both my password manager, but also the place where I keep track of notes about devices, accounts and software licences.

I tried to change over to Bitwarden a few weeks ago, because that is what my office wants us to move to, but the limitations are not really bridgeable for me. Bitwarden seem to me to be very specifically a password manager and not much else.

Be sure to make regular backups of your data.
… and using RAID is not a backup.

Great that it seems to work for you, but I’ve been experiencing this bug for months now if not longer.
I made the changes OP suggested, and now it seems to work correctly.

The problem is not that it gives a download prompt, but rather that it tosses the PDF file into your downloads folder unrequested.
It opens the PDF in the internal PDF viewer as well, but that is not the thing people are having issues with.

I don’t know whether they fixed it since, but last I checked that option was broken.
No matter what you select, half the time it still downloads the PDF to your drive.

How would one realistically go about testing their backup? Do you need a bunch of empty drives?

All my devices get named after cities. I try to make it somewhat relevant to the purpose of the machine.
Usually things related to the device (e.g. network shares) get named after neighbourhoods in the respective cities.

• Main PC: SAN-FRANCISCO,
• File server: SARAJEVO,
  • Shares: VRATNIK, BISTRIK, SEDRENIK, HRASTOVI,
• Work laptop: SEATTLE,
• Phone: BARCELONA,
• Media box: CANNES.

My boyfriend names all of his devices after planetary bodies, much like OP.
Thing related to the devices are named after the moons of the respective planet.

• Main PC: SATURN,
  • Drives: ATLAS, PROMETHEUS, TITAN, HYPERION, JANUS,
• File server: JUPITER,
  • Shares: GANYMEDE,
• Phone: PLUTO,
• Laptop: CHARON.

(He just realised that last one is inconsistent, and is renaming it to MERCURY)
