Hello all I can find is the cardano-cli help and https://github.com/input-output-hk/cardano-node/blob/master/doc/reference/cardano-node-cli-reference.md/ I am trying to get information on things like what --tx-out-datum-embed-file FILE does

This is a cop-out answer, but in my experience there surest place to go for answers is to read the source code directly.– waalgeCommented Feb 24, 2022 at 9:24

The flag --tx-out-datum-embed-file FILE allows you to embed the datum data on the transaction, not the datum hash like using that flag --tx-out-datum-hash-file FILE.
cardano-cli transaction build --tx-out-datum-embed-file DATUM.json
According to this web page, the definition is vague: The script datum to embed in the tx for this output, in the given JSON file. The file must follow the special JSON schema for script data.
I totally agree with you that a topic on datums/redeemers in JSON format for Tx is undocumented. However, I managed to find a very interesting GitHub post, which, I hope, will shed a light on some unclear things – Here it is. Unfortunately, that's all I could find on this topic.

1I Appreciate the reference. I still wouldn't know how to actually create a json file that can be directly uploaded from these. Like would I put the path to an arbitrary file in the fields value of another json file, or do I have to encode to cbor first. Its all very incomplete– noone392Commented Jan 10, 2022 at 0:13

I'm trying to learn this too. I could not find any further documentation other than the cardano-cli command help. This is pretty extensive and useful. Every command argument seems to have built-in help. So, for instance, to get help with building a transaction, issue the command cardano-cli transaction build. The help for this includes some info on the --tx-out-datum-embed-file FILE arguments.
