Peptide ligation by chemoselective aminonitrile coupling in water | Nature is one example of forming simple peptides under reasonable abiotic conditions; Nucleotide Selectivity in Abiotic RNA Polymerization Reactions - PubMed forming simple nucleic acids. Obviously, these are short of the structures needed for life; what they do demonstrate is that monomers can attach together under reasonably mundane conditions. More generally, organic chemical reactions happen and produce a wide variety of molecules. Of course, only certain ones are useful for the development of life. But simply building various molecules is not overly difficult.
Chiral molecules reacting generally produce chiral results - that part is rather mundane organic chemistry, so I’m not sure what sort of reference would be needed. Yes, several factors have been demonstrated to favor one stereoisomer over another; some of them are mentioned in the discussion at The origin of homochirality | Feature | Chemistry World. Molecules of opposite chirality tend to get in the way of polymerization (as discussed in that article, though it also notes exceptions). But, given the variety of possible natural ways to produce non-racemic mixes (such as those observed in meteorites), having a majority of one stereoisomer somewhere can promote further reactions biased towards a particular isomer. The abiotic soup would not need to be completely homochiral. Most biomolecules are homochiral, though exceptions exist and there are many achiral components as well. But that does not mean that the environment would have to be homochiral. After all, life today manages OK when encountering racemic mixtures.
The precise question is key. Do we have an exhaustive model of how all the necessary biomolecules formed and came together in the creation of life? No. But the formation of those molecules follows the basic laws of chemistry - there is nothing about them that could not in principle occur in some sort of primordial soup setting. This is a “glass half full or half empty” type of issue. Investigation into abiogensis is making slow but steady progress in coming up with possible ways that various steps could occur. It’s not running into a brick wall. But it is going into a fog, which could be hiding all sorts of obstacles.
