As I see it, it's difficult to tell whether having different shield types are the way the Frontier team are going.
I think there are more interesting ways they could make combat ship design more involved. Their concept as of the time of FFE (and it seems common with the rest of the 'Elite' series) is that everything you buy is essentially self-powering and recharge rates are independent from each other.
What would make a far more fundamental change would be if you factored in power generation, power consumption, and power storage on a ship-wide basis (for instance) you could treat your ship a bit like the human body.
Background Power Generation - Converting food to usable energy - Hydrogen Fuel
Power Storage - sugar in the blood, muscles, etc - Battery packs
Background Power consumption - Breathing, normal thinking - Ordinary Systems Consumption (Scanners, running lights &etc)
Extra-ordinary Power Consumption - Firing weapons, running with raised shields, jumping, hull repair systems &etc)
Why? Depending on how it's implemented, it adds more interesting dilemmas.
So when you fire your weapons it depletes your overall energy storage, rendering (for instance) your shields less resilient. This might stop people blatting their lasers everywhere, and instead switch to less power consuming kinetic projectiles if it looks like it's going to be a long fight (unless you're beyond the frontier and want to conserve ammunition).
Maybe you have a Plasma Accelerator, but to use it you have to take your shields practically off-line because it consumes so much damn power.
Do you maybe put an additional power-plant or high-capacity battery pack on your ship (in concept a little like the laser cooling booster or energy booster, but combined and maybe in addition to...) which gives you that unexpected combat boost that turns the tide against the pirates.
If it's balanced correctly, and the annoying elements are automated (like switching your drinks cabinet off when you're in combat mode, or a better example) that kind of system could be one possible basis for making personal ship design really interesting.
All I'm saying is that 'different types of shields' is a pretty small ask. I'm pretty sure we'll see Frontier delivering some more fundamental changes and enhancements to their system than that. I hope so, anyway.
