this is an amazing setup! i'd love to get a detolf but we just don't have space.
yes, i'd definitely wait a bit to rearrange or do any cleaning, since he is still settling in. because your cage is so large, you probably won't have to clean very often, especially if he's using the sandbath as a toilet. you'll probably never need to do a full clean, at most just a half clean, but certainly not for a while yet.

with the cork tunnel, i've seen people put them where their bedding slopes down? like as a kind of divider, but it seems that you have the Knuff there so i'm not sure if that would work. also if you want to create more space to add more things, you could get a larger sandbath and put the wheel in the sandbath. then you also wouldn't have to deal with getting bedding in the wheel (don't know if that's a problem for you but it is for me lol).

and i don't think there is anything you should change right away, your setup looks really good!
