In the following are some references that maybe helpful:

1. The majority of the lecture can be found in

https://arxiv.org/abs/1709.04891

In particular, the constraints from consistent interaction of massless states can be found in section 3.1. The discussion for massive higher spin and its constraint is in 5.2.2. Finally the discussion on the Higgs mechanism is found in sec 6

2. The discussion of anomalies in an onshell view point can be found in

https://inspirehep.net/literature/1242691

3. A recent Macine learning approach on CFT bootstrap, which can be applied to S-matrix can be found in

Cliff Burgess (McMaster and Perimeter)
Title: EFT in Inflation PDF

As to reading materials, I will make my slides available once they are ready in final form (so students need not worry about transcribing what I write in them).

There are also a variety of lecture notes they can use. I will follow quite closely these

https://physics.mcmaster.ca/~cburgess/Notes/InflationEFTs.pdf

since they were my given mandate. Some general reviews of effective theories in gravity and in general are in

https://physics.mcmaster.ca/~cburgess/Book/Ch1-6SnippetEFT.pdf

https://physics.mcmaster.ca/~cburgess/Notes/GRET-jhep.pdf

These, and other possibly useful lecture notes on GR, QFT, the SM and cosmology, are available at my lecture-notes page:

https://physics.mcmaster.ca/~cburgess/cburgess/?page_id=630

For a review of Ostrogradsky ghosts see: https://arxiv.org/abs/1506.02210
The argument I made about why higher derivative terms are not a problem in EFTs is summarized in https://arxiv.org/abs/1404.2236. It has also been pointed out - in https://arxiv.org/abs/1709.09695 - that in practice the leading terms that do arise in scalar EFTs often in any case by accident have the Horndeski form, at least for the lowest few dimensions of an EFT.
