If Hex OS is touted as the accessible NAS platform, I think prioritizing services with broad appeal would make the most sense in order to attract more...everyday users; not just existing homelab users.
Getting infrastructure setup for the following would be incredibly helpful and would probably help a large number of users.
Audiobookshelf - Audiobook and ebook management.
Calibre - ebook management.
Plant-It - Plant maintenance and care reminders.
Home Assistant - home automation.
mealie.io - Recipe management.
Jellyfin - FOSS Plex alternative.
Actual Budget - personal finance management.
Romm - Retro title management.
Steam Headless - (This one is a stretch) a headless Steam streaming server.
