It’s mostly so that I can have SSL handled by nginx (and not per-service), and also for ease of hosting multiple services accessible via subdomains. So every service is its own subdomain.
Additionally, my internal network (as in, my physical LAN) does not have any port forwarding enabled — everything is over WireGuard to my VPS.
Add to that photo editing (as much as GIMP is great…). I would guess DAW and video editing would fall under that category, too…and good luck finding many AAA open source games.
