Offering my experience as an example: I’m a software moron (fine at building a pc, crap at using it) and TrueNas Scale was simple to install and then access on mobile, tablet and via windows PC, at least as simple network attached storage.
When I tried to use it to just jellyfin I hit a brick wall, completely unable to understand how to use the shared datasets.
But as NAS it’s simple with a bookmark to manage.
I’ve used expressvpn on an Asus router, using fusion to split different ip addresses onto different vans and its been sound, no issues. So much easier than I was expecting.
