I see a multitude of subject there :
You can divide your possessions in two categories :
1) Artifacts, to show off, they can be located in a remote, sanctuarized, location (hangar flair, trophies, your favorite outfit, ...)
2) Your assets (Ships, armor, weapons, supplies, cargo ... )
I think that your starting location will be your sanctuary, where you retire to rest between 2 working shifts
Regarding your assets I would break them down in 2 subcategories :
2a) Having your assets near you (Ammunitition, workhorse ship, ...)
2b)Prepositionning assets for specific activities (preparing spare retaliators at Microtech for Xenothreat, prospectors at CRU-L1 for mining ... )
To keep your assets near your main area of operation, I would suggest to get a big ship and use it as a mobile storage unit : you land your C2 Hercules loaded with a hundred of thousand of ammo clips, food, water ... maybee a spare ship ...
So that would only left the home location as a prepositionning point for all your spare ships.
As of now, I think that all landing zones have specialties (Crusader for mining, Hurston for Bounty Hunting, Micro tech for Touring, and Arcorp to melt your GPU).
So under this light, for 3.15, I would rather choose Hurston as I am more focused on Bounty Hunting at the moment.
But in the long term, If i was given the choice to choose a location to setup my hangar, I would choose an High Sec area with a nice vista (like Microtech, or Arccorp) knowing that I will be able to invest in other real estate (aka colonial outpost) in our main area of operation
