Best starting options for a minion-based necromancer playthrough?

I know that summoning in this game is underwhelming and suboptimal, but I mostly play for the flavor, if there are mods that enhance this playstyle, all the better.
From what I gathered, arcane fullcasters are the best option for me, since I'm going with the lich mythic path and that is what I gravitate towards anyway, but even then I'm having trouble deciding what I should be getting between wizard, sorcerer, arcanist and witch, since I'm completely new to pathfinder in general... There is cleric too, but I dislike playing divine casters.
On the topic of races, people seem to gravitate towards dhampir for this, but human seems better due to the extra feat, plus I feel like going lich from human feels a bit more impactful somewhat. Is cruoromancy worth it? And what about archetypes, should I even choose one at all?
I want to balance usefulness without losing too much of the flavor, taking multiclasses just for the mechanics but with an unfitting theme, for example...
