Is there any functional difference between these and regular phasers besides being blue, and can they be used on any ship? Wondering for appearance purposes.
They're the same and can be used on all ships.
But as the OP said, they cannot be upgraded for unclear reasons. That's the only disadvantage.
The Fleet version can be upgraded. The Dilithium store items are a relic of times long gone and are buggy. I still wait for us to be able to craft them...

The write up mentions the dil-store ones can't be upgraded (no idea why). I read the wiki before buying the Andorian ship and just skipped straight to the fleet store version, which upgrade normally.
It still suck ... they shouldn't have the andorians as nonupgradable .. it's like they completely forgot about those .. the cardassian ones are upgradable .. and yes I did the huge mistake buying before checking wiki.
I'm not actually trying to rub it in. By any reasonable standard they should be upgradable. And they probably will be upgradeable at some point as the bug-fixing broom comes around. The trick is speeding that up , and making do in the meantime. At least the fleet ones are fairly accessible (just ask in sector space for an invite to a fleet starbase that can sell them if your fleet hasn't gotten that far).

It's just that there are 100 other bugs that ought to be fixed that are currently higher up on their to-do list
If you ask customer support maybe they can take away your dil store beams and refund the dil so you can buy fleet ones? (Unlikely, but you can ask.)
Or TOS phasers on the exchange.
