I just installed Firefly yesterday, and I can say that the docker compose setup was easy. I've got no real opinions yet, just wanted to mention this for OP in case he reads your experience as it being easier. I imagine they're both easy.
I'm curious, when you say you stopped importing, does that mean you were getting info from your banks, and stopped doing that? Why did you stop? My next step was to set up the automated importer for Firefly.
