Hmm… don’t know. Was just an avenue to explore.
Re: option sets, tons of info in the below post. Bubble says there’s a speed advantage, but whether it’s noticeable in your case I don’t know. I like option sets because they are easier to work with when building. You can pick the option in the editing panel, rather than having to do a search for a constraint based on its name. Note though that they should only be used for fixed constraints that are going to remain relatively static; changing them requires you going into the editor and pushing a new version of the app.
