Wine for borscht

I thought I'd asked this several years ago, but can't find. So we invited friends and their beagle for dinner tomorrow, Fred and beagle can come, she is out of town. I sent an email to another couple, about that time I got a text from them asking if we wanted to come for borscht. So we agreed on dinner at our place- Fred brings appetizer, Marc and Annabelle borscht as primi, we're making duck confit over salad, celeriac/turnip/potato mashed, mixed mushrooms. I've got Champagne to go with appetizers, red Burg for duck. But for borscht I'm wondering any white options? My instinct is Burg/PN, but would love to have variety. She says it is made with a beef broth, and there's some meat from bones, but it's not one of those meat heavy borschts. I am ok if best plan is bubbles/PN/PN, but prefer variety

Loire Cab Franc could work. What about Trousseau?

Cru Bojo? Chianti even?

I do like David's Loire CF suggestion.

Pilsner?

2009 Breton Franc de Pied did fine, thanks
