I've tried a number of approaches to a personal data repo: plain text files, custom database tools, dropping everything in a file folder... My current approach - which I really like - is vimwiki saving to markdown instead of the default .wiki. it's on a self-hosted NextCloud instance, giving me access across all my computers as well as my phone. It's not perfect - I'm extending it with some standardized project templates and other things - but everything's ultimately text; it's self-hosted, so not dependent on a third-party service that might disappear; and I can easily extend it to meet my requirements.
