For the most part, I'm going for the "cheapest" upgrades -- that is, the ones that don't require carved crystals. Apart from that, I'm putting a priority on upgrading the Jewelers, since that boosts the speed of doing more upgrades.

It's worth noting that the time improvements from doing upgrades decrease as the upgrade level increases. If the "base time" for doing something is 1000 minutes in a level-1 structure, it will be 952.4 minutes at level 2 (47.6 minutes faster), 909.1 minutes at level 3 (43.3 minutes faster than level 2), 869.6 minutes at level 4 (39.5 minutes faster than level 3), 833.3 minutes at level 5 (36.3 minutes faster than level 4), and so on. Pushing a few structures to high levels produces less overall benefit than gradually building up all of them, if all of the structures are being used. And, as in other places, you need to look at your game habits -- there's not much benefit to boosting speeds if the crafted items are just going to sit around waiting for you to use them.
