I'm using gitea to self-host, works well for markdowns and code, but bad for anything that is binary(pdf,media files,etc), because of git, which really does not fit for binaries, and git-lfs is a PITA to use still
Have you tried git-annex? I found it to be a simpler, more git-like solution to the large binaries problem than LFS, which seemed like a centralised system that would be painful to set up.
I do the same. I have a gitea instance and all my text saved in markdown in there. I also enabled full-text search so I can find it again. On mobile (iOS) I use working copy as a git client, which handles all files just fine (and also supports git-lfs).
Most of the time I want to attach binary files to notes, so I thought about using a sync solution like NextCloud or FileRun (with syncthing) and just link to my files.
I have something similar (private github, but will move to self host soon).
The binary thing is a challenge for me as well as part of my filing includes always making copies of web sites and office and pdf to check for versioning and edits. I frequently try to remember or check if web sites changed info or released a new version so I need a link and a frozen copy. Git does not like this and gets real big, real fast.
