Help recommending operatic songs & arias! :)?

I’m a bass/baritone, and I’m studying with a voice teacher (and a very good one that I adore!) However, she has mainly taught sopranos / alto (at a “serious level”), and hasn’t really had any good male students (a few), so her knowledge of bass / baritone arias is lacking. Looking for suggestions of lesser known composers, and loosely categorized “beginner – intermediate” arias and operatic songs. Any that I like I’ll of course discuss with her if I’m capable of. (Italian, English, German only). Some that I know,
Non Piu Andrai
Finc’han dal vino
Se voul ballare
Deh vienni alla finestra
But who may abide the day of his coming?
(love the runs!)
