Couple of points: Nurses get put upon. Will you leave on the dot at 1700? There are nursing jobs where you hand off to the next person on duty ie staff nurse, so when you go home you don’t have to worry about anything, but most of the 9-5 jobs the job has defined responsibilities. Even if one is off the clock there are still thoughts running around inside your head. It takes a bit of skill to be able to put them aside every day.
It’s really hard to fit everything you need to do at the weekend on a 9-5 compared to the flexibility of shifts. You have to be rigorous in terms of doing personal work in the evening after the job has finished.
Tbh have to look at career progression as well. Its not a straightforward choice.
Pretty sure truenas scale can host everything you want so you might only want one server. Use Epyc for the pcie lanes, and a fractal design r7 XL and you could even escape needing a rack mount if you wanted. Use a pcie to m.2 adapter and you could easily host apps on them on a mirrored pool and use a special vdev to speed up the HDD storage pool
The role of the proxmox server would essentially be filled by apps and/or VM you could turn on or off as needed.
