Escape Pods - merits broken. Some reports that finding Power signals is quite tricky in Acquisition systems.
Not seen that myself.
Power Kills - I've yet to see a Power ship in an Unoccupied. And it's a crime.
I've seen plenty in the signal sources. It's a crime, but it's a non-notorious one, so it can be reasonably effective and low-cost provided you have a nearby IF to use.
Holoscreen - is criminal for Acq.
Only a small fine, though. More of a problem potentially for the rep loss, but you have more merit-giving ways to recover that in Acquisition than in Undermining.
Retrieve Power Goods - aren't people reporting problems with opening these?
Works fine for me. There's the usual randomness of "does this container have 0 or 5 items" so it's a bit less reliable than data upload/download but it makes a nice supplement to them since you're there anyway and it can be done very quickly while running between data ports.
Scan Datalinks - yeah too hard, we've been discussing that today/yesterday; and very circumstantial.
It's pretty time-efficient, the catch is that you can only do it once per fortnight per megaship per commander, so only really works if there's a lot of people doing a small amount of work. Some big groups could potentially use it very effectively. But it's certainly a supplemental activity, not one to grind in isolation.
Sell mined resources - very dependent on the system.
And also for Acquisition, very dependent on the supporting system, given the unusual location requirements. On the other hand if you pick your future supporting systems to push to Fortified with their mining opportunities in mind, you can tip those odds heavily in your favour.
(Core mining is generally a bit more reliable than laser mining in this respect, though laser mining seems better if it works)
Sell rare goods - merits broken. Also supply-constrained.
Supply-constrained wasn't a massive problem given the old payout per-tonne, though who knows what state it might eventually come back in.
Transport Power Commodity - requires the right system under 20ly away, quite a lot of gaps in the map at the moment...
Though by definition any system which is a valid Acquisition target for your Power
does have at least one suitable system to get the commodity from. The problem here is that the allocation quantities even at rank 100 are so small it can only - again - be a supplemental source for something else.
You've missed Bounty Hunting as an Acquisition option - easy, generally available though some systems are certainly better than others, nicely positive for rep and credits too.
The other thing about Acquisition is that the targets are fairly small - 35k control score to get to the Conflict stage (which then opens up CZs if contested for
lots of Power Kills), and a minimum of 120k control score to Acquire it (which is all you need if it's not contested). You're also opposed (if at all!) by other people also doing Acquisition so it's a mostly-even fight in that respect (subject to the system having an environment which favours one or the other of you for ethos bonuses)
