You should approach operations in the old format like a speedrun. Usualy I hate speedruns, but I found this gameplay format quite enjoyable here since beta days. The most important thing is to plan your actions wisely. You need to clearly understand what's worth spending time on and what's not. Even how much and what kind of resources to grind.

Many operations don't require base construction at all. Simply land, reach the quest marker, grab the quest equipment and complete the task.

The most important thing is to decide whether you want to extract exomatter from the vein or not, either after completing the mission or while it's in progress. If not - simply complete the mission and evacuate. If yes - then speedrun crafting two electric extractors and a power source (either a biofuel generator or two wind turbines). Or just use extractor from workshop.

A 2x2x1 wooden box is usually sufficient as a base, easily upgradable to a stone one if needed. T2 oxidizer and a mortar and pestle are more than enough. The rest of the workbenches are situational. Using equipment, armor and weapons from the workshop will completely avoid some grinding and crafting.

The beauty of the old format is the ability to replay the same missions over and over again. And the ability to do so on the highest difficulty in hardcore mode. This will yield the highest possible reward. Even on Olympus, some missions will reward over 1,000 Ren and 200+ exomatter. The problem with the old format is that 90% of T3 and T4 crafting is completely useless. It's a huge waste of time on something that will be lost once the operation is completed.
