Is there a limit on how long the text can be for a text replacement shortcut? Prior to iOS 12.1, I had several shortcuts that would be replaced with two or three paragraphs of text. None of them work anymore. Shorter shortcuts (for things like emails, addresses, and short phrases) continue to work just fine.

Seems like a really silly design choice. Much like OP, I had shortcuts that stored large cookie-cutter responses. Updating iOS (which is supposed to be an upgrade) feels like a regression this time around.
Experiencing the same issue here. I can't pinpoint when exactly this started, but I believe it happened with the latest iOS update. This is a huge bummer. If there is a limit on characters, then alert me of that limit as I am creating the text replacement. As it stands, this looks more like a bug than a feature. Hoping this gets resolved.

It looks like this may be a new bug. Anything longer than 128 characters breaks it.
I don't use large text replacements, and I have not seen anything describing a change from Apple, however I did see a post in the last week addressing a similar question. You may want to search "text replacement" in the forum and see if you can locate it. Seems the user there was doing something similar to what you say about long strings of text.
Otherwise, to get an answer from Apple, you would need to use the Contact Support link at the top of the pages here.
If you search for the other posts, you will see that Apple Support has indicated to multiple users that it now restricts text replacements to 128 characters or less. That is by design.
Limits on Text Replacement?
