I don't self host anything except my NVR for CCTV, and a personal site on a cheap VPS using DokuWiki. I suppose you could kind of consider SyncThing self-hosting. I make pretty heavy use of that to keep my music collection on both my phone and my laptop, and to keep small important files mirrored on all my devices. I do want a NAS, but I have no immediate plans to get one, nor any idea of what tech I would use. Most likely a commercial WD or Synology to make things easier, or a device in the same kind of class as a Pi Zero W 2. Hopefully there will be tech like SyncThing-lite again soon, that can make a NAS usable P2P without any manual admin. Anything more than zero maintenance is too much, because I can't predict when something will have issues, and it might be while I'm away. The cloud alternatives have full time. I don't tend to switch SASS a lot, because the big services don't really change much, except chat platforms, but I don't have much choice there. I don't know many people who use anything that even could be self-hosted.
