From the past versions I played, I have made different play styles in the form of different pilot builds.
From your preference, it is very much possible for you to be the admiral at the seat, commanding even your own flagship orders that the AI crews follow most of the time. Just be aware that certain ship hull classes and weaponry may be used in a way that you are certain would lead to certain death. That usually falls to highly maneuverable low-durability frigate-sized ships or cloaked ships. The Hyperion class is the ship often addressed as not-so-good idea to be put to AI delegation and better done as a player flagship who likes being in the thick of battle. Lashers are reasonable ships early game under AI control so long as they have the right weapons mounted for effective AI combat. Hegemony ships have the armor to take a beating and, in my opinion, good ships for AI delegation in early and mid game.
Carriers are nice to use, just know which spacecraft mix to bring along. There is no need to repurchase squadrons when all are killed in battle as long as there is a ship with at least one hangar bay that can service and deploy them. Crew will still perish, however, and can be pricey in both supply and manpower, so must have a stable plan of earnings in your strategy should you take the route. I usually have the squadrons manned with green crew members, leaving the most experienced personnel manning the largest ships to optimize its combat performance and readiness, which is done by placing the ship in Logistic/Crew priority. The path also needs the use of Leadership abilities to increase the amount of orders to give as well as maximum logistics a fleet can handle.
In short, my self-taught techniques in AI delegation and fleet combat involves using durable ships with the right weaponry and setup AI crews can handle, in addition to staying aware of expenses expected in engagement and downtime. Would be a shame to have a carrier fleet only to be mothballed and stowed just to save what little credits are left. I played the armchair admiral in one of my builds, not assuming direct control of my flagship, and just watch as the fleet wins under my directions. It's one of those builds I enjoy from time to time.
