Well if you like to cheat in a simple way just the cheaty features of dfhack, it seems to be usually added with any pack you download from scratch. Some very cheaty features in it:
Before having even embarked you can use "prospect all" and dfhack counts the amount of diffrent types of ores there will be if you embark there, can also used when you have already embarked.
You can use createitem to create much of the base items used in production. There is an explanation
on it in the wiki. Edit: Just used this when I tested the features out and it crashed the game every fourth time or so for some random reason. So just save the game before you use it and it should be fine. It also tells you if you have done something wrong when it asks for stuff, such as not existing material or so.
You can make the selected dwarf much stronger or mentally capable using elevate-physical or elevate-mental.
Make-legendary (skill name in the list) makes the dwarf instantly a legendary skilled in said skill.
You can destroy all invaders using exterminate, destroy all undeads using "exterminate undead", or just destroy a specific creature using "exterminate him"
You can also use cursecheck to check if there is a vampire somewhere in the fort.
You can change the type of material there is in a vein using changevein and then the name of the inorganic material, such as RAW_PLATINUM or MAGNETITE.
clean all instantly removes all the filth without the dwarves having to clean themselves. This is the only one I use myself since the dwarves are dont clean themselves properly and the filth can multiply and drain fps.
You can use drain-aquifer and it will as you probably guessed, instantly drain all aquifers.
And much more... Its all listed
here and how to use it properly. That said the game quickly gets very boring if you cheat.
