Ok. So... drink the leftovers the next day. That’s easy. 😜
Champagne: Blanc de Blancs. Not too oxidative. There are dozens of producers I like here, but Taittinger Comtes is a great option if the price is ok. Frankly, despite being somewhat pricey, I think it is one of the best values in Champagne. ‘06 — which is still on many shelves — is great for it, too. Pierre Peters Grand Cru BdB Cuvée de Reserve is excellent for a bit less. I always like Pol Roger Blanc de Blancs in between those prices, and adore the Pierre Peters Chetillons I’ve had. Haven’t tried the ‘11 yet, though. But, leaving aside Selosse, Salon, and Krug CdM, there are still so many other good ones out there, too. (And I don’t even think the Selosse style would necessarily be a good pairing with your first course.)
I think especially with the bacon in your second course you’re exactly right on white Burgundy. Girardin 1er Vineyard designate Meursaults are great deals. His Corton Charlemagne is awesome. (The C-C Quintessence is sublime.) Pierre-Yves Colin-Morey 1er Cru single vineyard St Aubins are excellent. As are his more expensive offerings. Again, I don’t know your price range so it is hard to say. A little more expensive: Comtes Lafon Meursault les Charmes. A little less: Kumeu River Chardonnay Hunting Hill. (Mate’s and even the basic Estate “Chardonnay Kumeu” are also good.)
The Porto sauce with the veal cheek (mushrooms) is slightly problematic but leaving that aside you could go red Burgundy, Cru Beaujolais, rustic Rhone (north or south), rustic Barolo. I’m sure the Roda I would be great, though Spanish wines didn’t really come to mind. I love that wine, though. But the two specific wines coming to mind are Burlotto Monvigliero and Jamet Cote-Rotie. There are plenty of less expensive Roties that would also work. Just wouldn’t go too extracted. Same goes for the Nebbiolo. CdP just keep it more rustic. Pegau, Donjon, etc. I love Pegau. Probably you either already have appropriate red Burgundy or you don’t. But if you have access to Domaine des Lambrays CdL with a little age or Bachelet Corbeaux with a little age or de Montille 1er Cru Volnays with a little age, those are some non astronomically priced Burgs that I love. But, hey a Foillard Morgon Cote du Py would also work. In fact, but for the Porto sauce on that mushroom side, if you were drinking a really big white Burg, you could stick with it...
A million other wines would also work. I gave specific suggestions since you asked, and guessed at your price range, but I think you were on the right track.
