For congregational involvement, I imagine your hymn book includes Psalm 33 with antiphon/response Taste and see that the Lord is good. As shown in OCM, that can always be used at Communion, choir/schola, or just one cantor, on verses and congregational response for which they do not need the book.

Possible seasonal options for Advent -- maybe Ecce virgo (Behold, a virgin shall conceive and bear a son) or Jerusalem, surge (Arise, O Jerusalem, and stand on high)

I recommend establishing firmly in everyone's minds from the start that seasonal antiphons are interim while you work toward having the skill to execute the communion proper to each Sunday.

As you get accustomed to the seasonal/generic antiphons, a next step could be adding in seasonal psalm verses as well. Communion antiphons are short more often than not, and short antiphons can feel sudden, but with the addition of psalm verses become meditative. It's good skill-building for the schola too.

IME communion antiphons tend to be either very simple or strangely difficult. A further step could be to identify and tackle the simple ones while continuing to replace the tricky ones with something everyone is used to.

I recommend establishing firmly in everyone's minds from the start that seasonal antiphons are interim while you work toward having the skill to execute the communion proper to each Sunday.

And keep in mind that the Graduale Romanum itself provides for the opportunity to replace within a season any chant by another from the same season (see page 13). That puts ‘proper to each Sunday’ in another perspective.

I’m sorry, I forgot to quote the direction on page 13 of the Graduale Romanum. It’s on the title page of the Proprium de tempore and says:

In omnis Missis de Tempore eligi potest pro opportunitate, loco cuiusvis cantus diei proprii, alius ex eodem tempore.

Which reads, ‘In all Masses of the Season, another chant from the same season may, when appropriate, be chosen in place of the proper chant of the day.’

Though, for the vast supermajority of places in the USA, would it be a less preferred option than what has long been typical, namely, hymns/songs?

It's not an angle I'd push with a reluctant or indifferent pastor, as it would have the effect of making seasonal antiphons not worth bothering with and instead continuing with the typical.

There are seasonal Communion antiphons (along with seasonal Entrance antiphons) by Charles Thatcher in the 5th Edition of the St Michael Hymnal and I believe you can also get them from GIA here

(English again)

Another option besides seasonal, especially if your parish has a pew missal with the texts of the antiphons, is to use (or write) simple settings which are musically repetitive, so (like the simple Mass ordinary) the tunes can be memorized and applied to any text.

If the Chabanel propers are still in print (CCW), I seem to recall they had simple tones for the whole year (i.e., one tone for all the introits regardless of text). Although I'm happy to be corrected if I'm misremembering. In any case, pointing the antiphon to a simple psalm tone yourself is pretty simple.

One step more complex, but not as diverse as the simple english, is a complete set of entrance/communion propers we use at my parish by Martin Foster. He varies the tone a little (by season and a few for OT), so it's not overwhemlingly repetitive but the tones stick around for 4-8 weeks so if your choir or congregation learns fast that might be an option. They are written as accompanied/SATB voicings, which are often crunchier than they need to be, but can also easily be done solo.

I see that many people have more musically relevant handles. I should have picked 'Josephus' but I'd better stick to what people have seen now :)
