Another vote for actual. It’s my first budgeting app so I don’t have anything to compare it to, but it was super simple to set up (as far as self hosted apps go), I really like the web ui, and simplefin works to sync with all of my banks/accounts. My only gripe with it so far is that it could probably use a better mobile experience.

This doesn’t exactly answer your question, but I use the binhex qbittorrent-vpn image for this. It might work for you too unless you were wanting to be able to reuse the same wireguard container for something else?
