This guy was running a three year old version of Plex with a known (and later fixed RCE), and was working for LastPass.

It’s up to you how much you want to pay vs. how much time you are willing to sink into it. A synology is overpriced and underpowered, but you get a nice plug and play solution eith sane defaults. I went with that, fully knowing that price-wise, it’s not optimal. But I don’t enjoy tinkering as much as I used to.
