Hi Alexander,
yes, the overall shots provide a coherent framework for the whole structure and the closer shots provide the fine detail. You need to experiment to find the best workflow. I think you have plenty of prior input now… 
Don’t worry too much about the targets. You can just make your own, if needed. You can also use pencil crosses on a sticker. Never mind what, the only important aspect is the precision, whith which you measure those targets, and how well they can be identified on the images. The Chilitags (there are also Apriltags) you linked to are only important, if you want automated identification, for which you will need separate software.
