Maybe, but even experienced devs seem to want to fall into the trap of thinking their expertise will mean they can skim review AI code and spot it’s mistakes rather than taking the time to properly review and understand the code. Low effort is low 3ffort regardless of your expertise.
I think anything over the “assisted” threshold in the OP is low effort and should be dumped.
So all the bad things of both, still a proprietary product that you can funnel your cotent through servers you don’t control while simultaneously not being plex.
The misunderstanding that funneling your data through plex servers is functionally equivalent to exposing it to the internet.
Of the options I would say 2 but you forgot option 3, have a hardware router handle it and trunk the ports to the proxmox hosts.
