As is so often the case: no chains, but not easy, many little steps — very nice.

 hard work for me
after Setti 2,3,6 and xwing8 see no progress
Then BCD 6 must be high, otherwise conflict in the upper left
then B3 could not be 1, otherwise conflict in the upper left

 Same here. Confused myself massively, got there in the end by similarly to hp.
Question for the pros here, is there a logic way to 'see' the solution in BCD6 or is it simply a matter of running through the options?

Both options on b3 lead to the same solution on d6

 Nice one, but challenging and chainy. First nothing was happening, but later on both option in E5 show that E6 is low and that E5 can not be 8/9. At the end A3 high gives a short interaction in Box 2.

 Does not appear chainy to me, but needs VCE.

 Like Martinus, VCE is enough to solve, mainly in boxes 1, 5 and 9.
