the last time i touched a2jmidi, it did precisely what you were looking for
- 1 period of latency, zero jitter.
however, i do not maintain a2jmidid (it is not my project) and i have no
idea what has happened to it since I last did any work on it.

yes, absolutely. the only reason that -X raw and

removed is that the code to replace them isn't ready. always use a2jmidid
(with -e to pick up external h/w ports).
This made me have a look at the sources.
Up to ten minutes ago I was believing that a2jmidid used timestamps etc.
to reduce jitter, and that this made it preferable over Jack's -X.
But apparently it doesn't, all events in the same Jack period are
just bunched together. There's even a comment in the source code:
/* -FIX- this should have the frame time of the event, instead of '0': */
So what is the advantage ?
