Salve Regina by Poulenc
Lorenzo Perosi was a big deal around turn of the 20th century. Some of his music is still sung by the Sistine Choir

Can confirm, Perosi has some great stuff.

I really like Paul Jernberg as well, and Kevin Allen.

We also love Trisagion for Roman Hurco (I think, I will have to check to spelling and will come back and edit if that's wrong). It's tough to find, and definitely has an eastern flavour, but just works so well, especially if you have a decent low voices section.

Bernstein wrote a Missa Brevis late in his career. It sounds challenging, but in the right hands . . .

There’s the Vaughan Williams Mass in G and the Ropartz Messe “Te DeumLaudamus”

Finally for something rather recent, there is the LaRocca Mass for the Americas which has a version specifically written for the EF.

Arvo Part has some lovely pieces but the ones I am thinking of are in the vernacular... The Deer's Cry, and I am the True Vine.

Ave maris stella by James Macmillan is fantastic, but comes with dissonances that might be seen as mildly adventurous for the TLM.

There's a Latin version of Rachmaninoff's Bogoroditse Devo on CPDL, which might be worth investigating.

Oh, I like that Ave Verum. And you're right, there are other occasions where vernacular will be an option.

There are some very nice and fresh little motets by Alan Hovhaness which would be just the thing for young choirs. One that comes to mind is 'Praise Ye the Lord', which would be nice for a special day. These are about three or four pages long and are in 'motet' style with easy imitation. They are about as difficult as 'If Ye Love Me'.

There's one that I haven't sung yet but is on my "to do" list - If Ye Love Me by Philip Wilby. I love the Tallis one, but the Wilby intrigues me to no end.

Thanks for the plug, rich_enough

Obscure guys worth a look, stating with the US:
Bruno Oscar Klein (1858-1911). Student of Rheinberger (who should also be on your list) and doesn't fall far from the tree. His Beati Omnes (Op. 29/1, 1891, SATB org, at cpdl) recaps the Proper of the Nuptial Mass without actually being the Proper. Most of his motets are not readily available, but the Ordinaries, especially the Christmas mass Op. 44 (imslp) are worthwhile. The things for women tend to be less strong musically.

Eugeniusz Walkiewicz (1880-1946), active in the Midwest. The earlier works are more interesting. There's an Ave Maria SATB org. which is nice. Ordinaries range from the St. John Cantius Mass Op, 38 which to me is everything a mass for 2-equal and organ should be, to the Missa in honorem S. Josaphat Episcopi et Mart., Op.45, in 7 parts, a workout for any choir.

Germans:
J. K. Aiblinger deserves more love than he gets. Sort of the missing link between Michael Haydn and Rheinberger

There's been a minor renaissance for Max Filke, largely due to Nick Botkin.

Elsewhere:
J.M. Nunes Garcia of Brazil. There's a nice little Immutemur Habitu setting SATB, and a lot more. Haydnesque, but with a softer slightly ethnic flavor.

George Malcolm's Missa ad praesepe

Domenico Bartolucci wrote a lot of music, most unknown, not all compelling perhaps. But I've always been a sucker for his Crux Fidelis.

Daniel Knaggs has written >20 Ave Maria settings and some Ordinaries

Frank La Rocca's "calling card" piece tends to obscure his other Mass settings, and his motets, of which I have done and can recommend Diffusa est gratia.

I could go on. So much music, so little time, so few singers.

The Swiss composer Johann Baptist Hilber (1891-1973) wrote several effectful and reverent masses, which are quite accessible for rural parish choirs. Some movements have sections reminiscent of Gregorian chant. Here is an example.

I (and my choir) ADORE Francis Xavier Witt and Rheinberger! There are so many good options, but those two are absolutely divine!
