For anyone else wondering which PTA solution to try/choose, I found this summary: https://plaintextaccounting.org/FAQ#which-pta-app-should-i-c...

I think I'll finally give PTA and beancount a go this year. I'm tired of changing and re-learning tools due to enshittifcation, so I heavily prefer those that use open formats / plaintext. I use Obsidian for my notes, specifically because it's just Markdown files. Since I realized that I don't even really use most of Obsidian's features, I might just switch to a regular editor + a markdown viewer.
